description: Regarding the potential application of nanoscopic materials, the research focus is shifting towards three-dimensional anisotropic nanostructures. As a current example, this talk will introduce the importance of tetrapod-shaped nanostructures towards the engineering of smart 3D nanomaterials. A simple flame based single step approach was developed for the synthesis of zinc oxide tetrapods. These tetrapods have been used as building blocks to construct highly porous interconnected 3D nanoscale networks in the form of flexible ceramics. Additionally, these smart nanoscale networks can be utilized as sacrificial templates for the development of hollow tetrapodal 3D networks from almost any desired material (e.g. carbons, nitrides, oxides, polymers, hydrogels). The sacrificial template-based strategy offers new and unique opportunities in the construction of 3D nanomaterials, which will be demonstrated in this talk with several examples. Moreover, the potential applications of these 3D structured smart materials in the fields of sensing, electronics, optoelectronics, energy, and biomedical engineering will be highlighted.

description: Let X be a 2-dimensional, normal, flat, proper scheme over the integers. Assume ¯L and ¯M are two hermitian line bundles over X. Arakelov (and Deligne) defined a real number ¯L.¯M, the arithmetic intersection number of ¯L and ¯M. We shall explain the definition and the basic properties of this number. Next, we shall see how to extend this construction to higher dimension, and how to interpret it in terms of arithmetic Chow groups.

description: Let X be a subvariety of Pn defined over a number field and N(B) be the number of rational points of height at most B on X. There are then general conjectures of Manin on the asymptotic behaviour of N(B) when B goes to infinity. These conjectures can be studied using the Hardy-Littlewood method for non-singular complete intersections of high dimensions and by adelic harmonic analysis for varieties related to algebraic groups. But for most varieties there are no other methods available apart from sieve theory and determinant methods. The latter was first developed for affine plane curves in a paper of Bombieri-Pila and extended to projective varieties by Heath-Brown and myself. The goal of the p-adic version of this method is to show that the set of rational points of height at most B on X in a congruence class satisfy further equations if p is large enough compared to B. One can then proceed by induction with respect to dim(X) to obtain uniform upper estimates for N(B) like a proof of the dimension growth conjecture of Heath-Brown and Serre. The lectures will focus on the determinant method. We will make essential use of Mumford’s geometric invariant theory too see how stability conditions affect the equidistribution of rational points. This is inspired by Donaldson’s and Tian’s theory of Kähler-Einstein metrics. We will also explain how one can use the theory of volumes of line bundles in Lazarsfeld’s book to improve upon the original bounds of Heath-Brown. If time permits we will also mention a number of striking similarities between the determinant method and methods used in the theory of Diophantine approximation.

description: Chavdarov and Zywina showed that after passing to a suitable field extension, every abelian surface A with real multiplication over some number field has geometrically simple reduction modulo p for a density one set of primes p. One may ask whether its complement, the density zero set of primes p such that the reduction of A modulo p is not geometrically simple, is infinite. Such question is analogous to the study of exceptional mod p isogeny between two elliptic curves in the recent work of Charles. In this talk, I will discuss how to apply Charles's method to the setting of certain abelian surfaces with real multiplication. This is joint work with Ananth Shankar.

In this talk, we report on a formula that determines the special value at s=1 of the derivative of the Selberg zeta function for Γ=PSL2(Z). This formula is obtained as an application of a generalized Riemann-Roch isometry for the trivial sheaf on ¯Γ∖H, equipped with the Poincaré metric. This is joint work with Gerard Freixas.

description: Some themes inspired from number theory have been playing an important role in holomorphic and algebraic dynamics (iteration of rational mappings) in the past ten years. In these lectures I would like to present a few recent results in this direction. This should include: the dynamical Manin-Mumford problem, in particular in the case of product rational maps (P(x),Q(y)) (after Ghioca, Nguyen, and Ye) the “unlikely intersection” problem (after Baker and DeMarco, and also Favre and Gauthier). A key technical tool in these results is the equidistribution theory of points of small height. If time permits, we’ll also discuss the related problem of the equidistribution of roots of random polynomials.

description: The distribution of rational points of bounded height on algebraic varieties is far from uniform. Indeed the points tend to accumulate on thin subsets which are images of non-trivial finite morphisms. The problem is to find a way to characterise these thin subsets. The slopes introduced by Jean-Benoît Bost are a useful tool for this problem. These lectures will present several cases in which this approach is fruitful. We shall also describe the notion of locally accumulating subvarieties which arise when one considers rational points of bounded height near a fixed rational point.

description: In these lectures I will focus on the Riemann-Roch theorem in Arakelov geometry, in the specific context of some simple Shimura varieties. For suitable data, the cohomological part of the theorem affords an interpretation in terms of both holomorphic and non-holomorphic modular forms. The formula relates these to arithmetic intersection numbers, that can sometimes be evaluated through variants of the first Kroenecker limit formula. I will first explain these facts, and then show how the Jacquet-Langlands correspondence allows to relate arithmetic intersection numbers for different Shimura varieties, whose associated groups are closely related.

description: A Shimura variety is a higher-dimensional analogue of a modular curve that arises as a quotient of a Hermitian symmetric space by a congruence subgroup of a reductive algebraic group defined over Q. Shimura varieties have a very rich geometric and arithmetic structure. For instance they are defined over a number field (the reflex field), they have line bundles provided with hermitian metrics that come from a representation of a maximal compact subgroup and sometimes they have models over a localization of a ring of integers coming from a modular interpretation. Open Shimura varieties admit toroidal compactifications, but the mentioned metrized line bundles do not extend to a smoothly metrized line bundle in the compactification, but to a line bundles with logarithmic singular metric. Thus the usual Arakelov geometry can not be applied to them. In this course we will explain how to extend Arakelov theory to cover this class of singular metrics. Important applications of this extended Arakelov theory arise in the context of the Kudla program, which predicts deep connections between the arithmetic geometry of arithmetic special cycles on integral models of orthogonal and unitary Shimura varieties and the theory of Siegel modular forms. These connections lead to (often conjectural) generalizations of results of Gross, Kohnen and Zagier on Heegner divisors on modular curves. We will give an introduction to the Kudla program and discuss some cases where the predictions have been proved.

description: In the classical analogy between number fields and function fields, an Euclidean lattice (E,∥.∥) may be seen as the counterpart of a vector bundle V on a smooth projective curve C over some field k. Then the arithmetic counterpart of the dimension h0(C,V)=dimkΓ(C,V) of the space of sections of V is the non-negative real number h0θ(E,∥.∥):=log∑v∈Ee−π∥v∥2. In these lectures, I will firstly discuss diverse properties of the invariant h0θ and of its extensions to certain infinite dimensional generalizations of Euclidean lattices. Then I will present applications of this formalism to transcendence theory and to algebraization theorems in Diophantine geometry.

Arithmetic Intersection (Part 4)

uk: Математика, природничі науки

description: Let X be a 2-dimensional, normal, flat, proper scheme over the integers. Assume ¯L and ¯M are two hermitian line bundles over X. Arakelov (and Deligne) defined a real number ¯L.¯M, the arithmetic intersection number of ¯L and ¯M. We shall explain the definition and the basic properties of this number. Next, we shall see how to extend this construction to higher dimension, and how to interpret it in terms of arithmetic Chow groups.

description: Let X be an algebraic curve of genus g⩾2 embedded in its Jacobian variety J. The Manin-Mumford conjecture (proved by Raynaud) asserts that X contains only finitely many points of finite order. When X is defined over a number field, Bogomolov conjectured a refinement of this statement, namely that except for those finitely many points of finite order, the Néron-Tate heights of the algebraic points of X admit a strictly positive lower bound. This conjecture has been proved by Ullmo, and an extension to all subvarieties of Abelian varieties has been proved by Zhang soon after. These proofs use an equidistribution theorem in Arakelov geometry due to Szpiro, Ullmo, and Zhang. Using more classical techniques of diophantine geometry, David and Philippon have given another proof which, moreover, provides an effective lower bound. In the talk, I will present the equidistribution statement, and his powerful generalization due to Yuan. I will then give the proof of the Bogomolov conjecture following Ullmo-Zhang. If time permits, I will also describe the proof of David and Philippon. I then plan to introduce the non-archimedean analogue of the equidistribution result and its application by Gubler to the Bogomolov conjecture over function fields.

description: Digital twins are increasingly important in many domains, including for understanding and managing the natural environment. Digital twins of the natural environment are fueled by the unprecedented amounts of environmental data now available from a variety of sources from remote sensing to potentially dense deployment of earth-based sensors. Because of this, data science techniques inevitably have a crucial role to play in making sense of this complex, highly heterogeneous data. This seminar reflects on the role of data science in digital twins of the natural environment, with particular attention on how resultant data models can work alongside the rich legacy of process models that exist in this domain. We seek to unpick the complex two-way relationship between data and process understanding. By focusing on the interactions, we end up with a template for digital twins that incorporates a rich, highly dynamic learning process with the potential to handle the complexities and emergent behaviors of this important area. The seminar also considers the important role that Digital Research Infrastructure can play in underpinning digital twin development, including supporting FAIR assets to underlying data and modeling resources as well as ensuring federation between digital twin structures.

description: Xcube is an open-source xarray-based Python package and toolkit that has been developed to provide Earth observation (EO) data in an analysis-ready form to users. xcube achieves this by carefully converting EO data sources into self-contained data cubes that can be published in the cloud. In this session you will learn about the ecosystem around xcube, which allows to access different data sources and turning the inputs into data cubes. These data cubes can then be easily used for spatiotemporal data analysis and visualization. After a brief introduction about the software components, we will go step by step though some example Jupyter notebooks and finally we will dive into a hands-on session with a little challenge. For the session you will need a laptop with an internet connection, some basic knowledge about Python and already installed miniconda (https://docs.conda.io/en/latest/miniconda.html) which is used to download the necessary Python packages for the session. Prior experience with Jupyter notebooks will be helpful, but not mandatory.

It is built on top of GeoPandas and provides functions to analyze, manipulate and plot trajectories. To get a better idea of the type of analytics that MovingPandas supports, visit: https://movingpandas.org/examples DVC is a data version control (and machine learning experiment tracking) library. It follows a similar logic to source code version control systems (such as Git) and is typically used together with Git to keep track of data and experiments while Git keeps track of the source code. In this session, we will use DVC to keep track of our movement data analytics workflow. Participants are expected to come prepared with a working MovingPandas & DVC Python environment. Basic previous experience with (Geo)Pandas and version control systems (i.e. how pull, commit, push works in Git) is expected.

description: Satellite imagery time series offer a powerful means to detect and analyze both short- and long-term changes in the environment. In particular, the availability of open-access data from missions like Landsat (since 1972) and Sentinel (since 2015) has significantly enhanced our ability to study these changes. This workshop aims to explore the use of time series of indices derived from satellite imagery for analyzing various types of land cover changes using the programming language R. The workshop covered essential preprocessing steps, including outlier removal and handling missing observations, to ensure the quality of the data. Participants learned how to effectively model time series using different methods. Additionally, the workshop provided insights into detecting trends and breaks within the time series data. The analysis focused on a range of objects and encompass both abrupt and gradual changes. Examples of the types of changes that were explored include urban growth or vegetation succession.

description: The course will present applications of interpretive machine learning methods to geospatial analysis. Interpretive machine learning is a new branch of machine learning that allows the decomposition of black box models. It allows complex, non-linear models to explain the criteria that lead to a result. In the case of geospatial data, it can be used to search for patterns of spatial explanatory factors. The course covers the entire toolchain from data preparation, model training, and the data transformation process, through data analysis and interpretation of the results, to spatial visualization. The toolchain includes tools such as the shap library, selected components of the scikit-learn, geopandas, and matplotlib packages. The course includes a theoretical introduction to interpretive machine learning and how it can be applied to geospatial data. The practical part is built around analysing the U.S. presidential election results Clinton vs. Trump. In the first step, explanatory variables are collected and transformed into shapely numbers. The data transformed in this way will determine the relevance of the explanatory variables and their actual impact on the election outcome in each county. The advantage of shapely numbers is that the variables are automatically weighted, allowing for efficient clustering. The shapely numbers and their clustering results reveal interesting spatial patterns in the electoral process.

description: OpenStreetMap (OSM) is a free and openly editable map of the world. Like Wikipedia and unlike government or corperation maintained datasets, OSM is created and maintained by a community of volunteers, making it the premier decentralized and fastest evolving source of geographic vector data focussed on features relevant to human activity (e.g. roads, buildings, cafes) on planet Earth. Unlike Wikipedia, every data point in OSM has a geographic location and attributes must be structured as key-value pairs. OSM is a rich source of data for geocomputational research, but the decentralized nature of the project and the sheer volume of data. ‘Planet.osm’ now has more nodes than there are people on Earth, with more than 8 billion nodes, and the rate of data creation is increasing as the community grows, to 10 million users in early 2023. The size and rapid evolution of OSM are great strengths, democratising geographic knowledge and ensuring resilience. However, these features can make it difficult to work with OSM data. This lecture will provide an introduction to working with OSM and will cover the following: - How and where to download OSM data - How to process small amounts of OSM data using the osmdata R package - How to process large OSM ‘extracts’ data with the osmextract R package - Other command line tools for working with OSM data, including the mature and widely used osmium tool, the pyrosm Python package and the osm2streets web application and Rust codebase Finally, the lecture will outline ideas for using OSM data. It will conclude with a call to action, inspiring the use of this rich resource to support policy objectives such as the fast and fair decarbonisation of the global economy as societies transition away from inefficient, polluting and costly fossil fuels.

François Guéritaud, while studying work of Ian Agol, gave a powerful technique for turning a singular euclidean structure (on a surface) into a triangulation (of a three-manifold). We will give an exposition of some of this work from the point of view of Delaunay triangulations for the L ∞ -metric. We will review the definitions in a relaxed fashion, discuss the technique, and then present applications to the study of strata in the space of singular euclidean structures. If time permits, we will also discuss the naturally occurring algorithmic questions.

These representations have infinite images and give points on character varieties that are fixed by the action of the mapping. Moreover we can approximate these representations by representations into finite groups in order to build exotic regular finite covers of surfaces. These covers have the following property: the integral homology is not generated by pullbacks of simple closed curves on the base. This is joint work with Thomas Koberda.

description: The monodromy group of a translation surface M is the Lie group spanned by all symplectic matrices arising from the homological action of closed loops at M (inside its embodying orbit closure). In the presence of zero Lyapunov exponents, Filip showed that these groups are —up to compact factors and finite-index b groups— constrained at the level of Lie groups presentations: they are either special quaternionic orthogonal groups SO*(2n) for odd n, special unitary groups SU (p,q) for p superior q, or exterior powers of SU(p,1). Nevertheless, it does not follow from these constraints that every group in this list is realizable as the monodromy group of some translation surface. By the work of Avila–Matheus–Yoccoz, it is known that every SU (p,q) is realizable. Moreover, the work of Filip–Forni–Matheus shows an example that realizes SO *(6), which coincides with the second exterior power of SU( 3 , 1 ). In this talk, we show that the groups SO *( 2 n ) are realizable as monodromy groups for infinitely many odd values of n . To this end, we find concrete examples of square-tiled surfaces constructed as quaternionic covers —generalizing the construction by Filip–Forni–Matheus— having such groups as their monodromies (up to compact factors and finite-index subgroups). Our construction is valid for every n in the congruence class of 3 mod 8, up to a zero-density set.

Marked points in genus two and beyond

uk: Математика, природничі науки

description: In the principal stratum in genus two, McMullen observed that something odd happens - there is only one nonarithmetic Teichmuller curve - the one generated by the decagon. This strange phenomenon begets another - a primitive translation surface in genus two admits a periodic point that is not a Weierstrass point or zero only if it belongs to the golden eigenform locus. In this talk, we will explain how to leverage results of Mirzakhani-Wright to study the orbit closures of translation surfaces with marked points and sketch a proof of the previously mentioned result in genus two. We will also explain how the result in genus two proves another uniqueness results - that there is at most one nonarithmetic rank two orbit closure in the minimal stratum in genus four - the one discovered by Eskin-McMullen-Mukamel-Wright.

description: Tiling billiards is a dynamical system in which a billiard ball moves through the tiles of some fixed tiling in a way that its trajectory is a broken line, with breaks admitted only at the boundaries of the tiles. One can think about this system as a movement of the refracted light. In this talk, I will speak about a specific kind of such billiards: negative triangle tilling billiards introduced in the work by P. Baird-Smith, D. Davis, E. Fromm and S.Iyer. The tiling is a periodic tiling of a plane by congruent triangles (obtained from the standard equilateral triangle tiling by linear transformation). The law of reflection in any side is Snell’s law with the coefficient of refraction equal to -1. This system is, in a simple and magical way, related to interval exchange transformations with flips. I will explain this relationship and some results that follow from it. First, almost all the trajectories of such tilings are either closed or escape linearly to infinity. Second, there exists an interesting measure zero set of parameters for which the trajectories escape to infinity in a non-linear fashion, and approach fractals. This set is parametrised by the Rauzy gasket. My talk will be based on a joint work with Pascal Hubert, some computer simulations by Paul Mercat, and the article of D. Davis and her coauthors.

description: Finding lattices in PU(n,1) has been one of the major challenges of the last decades. One way of constructing a lattice is to give a fundamental domain for its action on the complex hyperbolic space. One approach, successful for some lattices, consists of seeing the complex hyperbolic space as the configuration space of cone metrics on the sphere and of studying the action of some maps exchanging the cone points with same cone angle. In this talk we will see how this construction can be used to build fundamental polyhedra for all Deligne-Mostow lattices in PU(2,1).

description: We will give the proof of Mirzakhani's theorem that the earthquake flow and Teichmuller unipotent flow are measurably isomorphic. We will assume some familiarity with quadratic differentials, but no familiarity with earthquakes, and the first lecture will be devoted to preliminaries. The second lecture will cover the proof, and the final lecture additional connections such as the link between Weil-Petersson and Masur-Veech volumes. If time allows, we will mention Mirzakhani's recent result on counting mapping class group orbits, which relies on her work on earthquake flow.

description: H. Masur showed in the early 80s that almost every Teichmuller ray converges to a unique point in PMF. It is also known since a while that there are rays that have more than one accumulation point in the boundary. I will give an overview of what is understood so far about the limit sets of Teichmuller rays, mentioning some recent progress. For example, I will mention recent joint work with K. Rafi and B. Modami where we give a construction of a ray whose limit set in PMF is a d-dimensional simplex.

description: While significant progress has been made towards explaining black-box machine-learning (ML) models, there is still a distinct lack of diagnostic tools that elucidate the spatial behaviour of ML models in terms of predictive skill and variable importance. This contribution proposes spatial prediction error profiles (SPEPs) and spatial variable importance profiles (SVIPs) as novel model-agnostic assessment and interpretation tools for spatial prediction models with a focus on prediction distance. Their suitability is demonstrated in two case studies representing a regionalization task in an environmental-science context, and a classification task from remotely-sensed land cover classification. In these case studies, the SPEPs and SVIPs of geostatistical methods, linear models, random forest, and hybrid algorithms show striking differences but also relevant similarities. Limitations of related cross-validation techniques are outlined, and the case is made that modelers should focus their model assessment and interpretation on the intended spatial prediction horizon. The range of autocorrelation, in contrast, is not a suitable criterion for defining spatial cross-validation test sets. The novel diagnostic tools enrich the toolkit of spatial data science, and may improve ML model interpretation, selection, and design.
