Max von Kleist (FU-Berlin Antrittsvorlesung): Mathematics for public health
Public health is concerned with measures that improve the general health and prevent infections. In my talk, I will give an overview and outlook of our current work and explain how data science in conjunction with mathematical modeling and simulation can be utilized to guide public health decisions. In particular, I will present approaches that utilize primary and secondary data of SARS-CoV-2 to permanently monitor and assess the pandemic. Moreover, I will give examples where these approaches supported the choice of containment and testing strategies in 2020/21. I will then give some insight into our ongoing work in the field of HIV-1 prevention, the mathematical methods developed along the way, and illustrate how this work is used to quantify risk reduction, to develop guidelines, as well as to a posteriori assess the impact of interventions on the HIV pandemic.

Marita Thomas (FU-Berlin Antrittsvorlesung): Modeling and Analysis of Bulk-Interface Processes
Heterogeneous materials can be seen as bulk-interface systems. They consist of distinct bulk components with different material properties meeting at thin interfacial layers forming lower-dimensional substructures of the system. In many applications the properties of interfaces strongly impact the functionality of the whole system and, in turn, interfaces are strongly affected by processes taking place in the bulk material. Interfaces thus follow their own evolution laws in interaction with bulk processes. In this talk I discuss a general thermodynamical modeling framework for bulk-interface processes and, in particular, apply it to problems related to heat conduction and fracture in elastic composites. Here, a challenge in the modeling and in the analysis lies in the change of the material geometry with the progressing fracture and in the constraint that in many materials crack growth is a unidirectional process, since the crack cannot heal. Models suited to handle these challenges and thus suited to describe dynamic fracture processes in elastic solids with the aid of non-smooth constraints will be introduced. Recent results on their mathematical analysis will be presented.

Claudia Schillings (FU-Berlin Antrittsvorlesung): Quantification of uncertainty for inverse and optimization problems
Approaches to decision making and learning mainly rely on optimization techniques to achieve “best” values for parameters and decision variables. In most practical settings, however, the optimization takes place in the presence of uncertainty about model correctness, data relevance, and numerous other factors that influence the resulting solutions. For complex processes modeled by nonlinear ordinary and partial differential equations, the incorporation of these uncertainties typically results in high or even infinite dimensional problems in terms of the uncertain parameters as well as the optimization variables. We will discuss methods which can be shown to be robust with respect to the number of parameters and are therefore suitable for this setting.

Milena Hering (Edingburgh): Embedding of Algebraic Varieties and Toric Vector bundles
Algebraic varieties are geometric objects that can be described as the zero locus of polynomial equations. While the relationship between geometry and algebra is fundamental to algebraic geometry, it still remains quite mysterious. I will explain some aspects that are known about it, as well as some open questions. And how toric vector bundles enter the equation.

Arend Bayer (Edingburgh): Derived Categories, Wall-crossing and Birational Geometry
Birational geometry studies maps between algebraic varieties defined by rational functions.

Ana Djurdjevac (FU-Berlin Antrittsvorlesung): Randomness and PDEs: Analysis, Numerics and Applications
We will first consider interacting particle systems that provide powerful models that are useful in many application areas such as sociology (agents), molecular dynamics (proteins) etc. The first model that we will define is a non-linear stochastic PDE that provides a faithful representation of the evolution of the empirical density of a given particle system. This model has a direct applications in the opinion dynamics that will be discussed. Furthermore, we will explain difficulties in numerical approximations of these problems. Instead of considering many particles, next we will consider just one Brownian particle, but which is now evolving on a random domain. Using the rough path analysis, we will investigate different scaling regimes of this system. As a natural question in this setting is how to present a Gaussian random fields on a sphere. One way to do this is using the so-called spherical harmonics. We will discuss the advantages of this approach and challenges in its generalizations to an arbitrary manifold.

Imre Bárány (Rényi Institute, Budapest): Cells in the box and a hyperplane
It is well known that a line can intersect at most 2 n −1 cells of the n × n chessboard. What happens in higher dimensions: how many cells of the d -dimensional [0, n ]^ d box can a hyperplane intersect? We answer this question asymptotically. We also prove the integer analogue of the following fact. If K,L are convex bodies in R ^d and K ⊂ L , then the surface area K is smaller than that of L . This is joint work with Péter Frankl.

János Pach (Rényi Institute, Budapest): Facets of Simplicity
We discuss some notoriously hard combinatorial problems for large classes of graphs and hypergraphs arising in geometric, algebraic, and practical applications. These structures are of bounded complexity: they can be embedded in a bounded-dimensional space, or have small VC-dimension, or a short algebraic description. What are the advantages of low complexity? I will suggest a few possible answers to this question, and illustrate them with classical examples.

Anna-Laura Sattelberger (Leipzig): Algebraic and Topological Data Analysis
16:30-16:50 Uhr Lehrprobe zum Thema The Theorem of Carathéodory (auf Englisch) ca. 17:00-17:40 Uhr Fachvortrag: Algebraic and Topological Data Analysis Algebraic analysis investigates linear differential equations with polynomial coefficients by encoding them as ideals in the Weyl algebra D . In this talk, I present several applications of this theory in the sciences. Among others, I present how maximum likelihood estimation - a technique from statistics for the inference of data - can be tackled in terms of D -modules. The second part of my talk is about the development of algebraic tools for topological data analysis. This area of research extracts intrinsic information of data with methods from (algebraic) topology. The main tool is persistent homology. While the one-parameter case is fully described by so-called "barcodes" associated to the data, one encounters a lack of a corresponding invariant in the multivariate case. I give insights into an ongoing project with Wojciech Chachólski and René Corbet, in which we construct stable invariants for multipersistence modules.

Alessio D’Alì (Osnabrück): Constructing Koszul Gorenstein algebras from Cohen-Macaulay simplicial complexes
14:15-14:35 Uhr Lehrprobe zum Thema The Theorem of Carathéodory (auf Englisch) ca. 14:45-15:25 Uhr Fachvortrag: Constructing Koszul Gorenstein algebras from Cohen-Macaulay simplicial complexes My main area of interest is combinatorial commutative algebra, a topic that sits at the crossroads between algebra, combinatorics and topology. The main aim of this talk is to discuss a joint project with Lorenzo Venturello (KTH Stockholm) relating Koszul Gorenstein algebras and Cohen-Macaulay simplicial complexes. Koszul algebras are quadratic algebras satisfying desirable homological properties and arising naturally in many geometric and combinatorial contexts: for instance, the coordinate rings of Veronese, Segre and Grassmannian varieties (in their natural embeddings) are all Koszul, and so is the Stanley-Reisner ring of any flag simplicial complex. However, the Koszul property is hard to control and to check in general, and many conjectures about the general behaviour of Koszul algebras are currently open. Starting from a flag pure simplicial complex Δ, we propose a construction of a (non-monomial) Gorenstein ring R_Δ which is Koszul if and only if Δ is Cohen-Macaulay, thus providing a bridge between these two worlds. On a more combinatorial level, the very same correspondence also yields that R_Δ has a Gröbner basis of quadrics if and only if Δ is shellable. As an application, we provide counterexamples to an algebraic generalization of a conjecture by Charney and Davis about flag homology spheres.

Marvin Anas Hahn (Leipzig): Die tropische Geometrie von monotonen Hurwitz-Zahlen
12:00-12:20 Uhr Lehrprobe zum Thema The Theorem of Carathéodory (auf Englisch) ca. 12:30-13:10 Uhr Fachvortrag: Die tropische Geometrie von monotonen Hurwitz Zahlen Hurwitz-Zahlen sind wichtige enumerative Invarianten in der algebraischen Geometrie. Sie zählen verzweigte Abbildungen zwischen Riemannschen Flächen. Äquivalent enumerieren sie Faktorisierungen in der symmetrischen Gruppe. Hurwitz-Zahlen wurden in den 1890er Jahren von Adolf Hurwitz eingeführt und wurden in den 1990er Jahren durch enge Verbindungen zur sogenannten Gromov-Witten-Theorie zu zentralen Objekten der enumerativen algebraischen Geometrie. Dieses Zusammenspiel zwischen Hurwitz und Gromov–Witten-Theorie ist ein aktives Forschungsfeld und brachte u.a. die gefeierte ELSV–Formel hervor. Im letzten Jahrzehnt sind viele Varianten von Hurwitz-Zahlen eingeführt und untersucht worden. Insbesondere die Frage nach Verbindungen zwischen diesen Varianten von Hurwitz Zahlen und Gromov–Witten-Theorie ist von großem Interesse. Sogenannte monotone Hurwitz-Zahlen , die der Theorie der Zufallsmatrizen entstammen, gehören zu den meistuntersuchten Varianten von Hurwitz-Zahlen. Dieser Vortrag ist ein Fortschrittsbericht unseres größeren Programms, in welchem wir die Verbindungen zwischen monotonen Hurwitz-Zahlen und Gromov-Witten-Theorie durch kombinatorische Methoden der tropischen Geometrie untersuchen und dessen langfristiges Ziel ein Beweis der noch offenen Vermutung einer ELSV – Typ Formel für doppelte monotone Hurwitz-Zahlen ist. Der Vortrag basiert zum Teil auf gemeinsamen Arbeiten mit Reinier Kramer und Danilo Lewanski.

Giulia Codenotti (Frankfurt): The flatness constant and its relatives
16:30-16:50 Uhr Lehrprobe zum Thema The Theorem of Carathéodory (auf Englisch) ca. 17:00-17:40 Uhr Fachvortrag: The flatness constant and its relatives The lattice width of a convex body is a parameter measuring how thin the body is in lattice directions. In each fixed dimension, the flatness constant is the supremum of the widths of a special class of convex bodies, those which are hollow. In this talk we will explore certain generalizations and restrictions of the flatness constant obtained by changing the class of convex bodies whose width we study: hollow lattice polytopes, for example, or those convex bodies which do not contain a certain polytope. We will see how these modified flatness constants have connections and motivations in different fields, like integer linear programming, lattice polytopes, and symplectic geometry.

Jorge Olarte (TU Berlin): Valuated matroids and regions of the tropical Grassmannian
14:15-14:35 Uhr Lehrprobe zum Thema The Theorem of Carathéodory (auf Englisch) ca. 14:45-15:25 Uhr Fachvortrag: Valuated matroids and regions of the tropical Grassmannian A valuated matroid is essentially a matroid polytope regularly subdivided into matroid polytopes. In tropical geometry, valuated matroids take the role of linear spaces, hence their importance. The tropical Grassmannian is the space of valuated matroids which are realizable, that is, they arise as tropicalizations of a classical linear space. Certain regions in the tropical Grassmannian have deep connections to certain types of matroid, such as positroids and transversal matroids. In this talk we will discuss three regions of interest: the positive part, the image of the tropical Stiefel map and the tropical symplectic Grassmannian.

Marta Panizzut (TU Berlin): Polytopes meet polynomials: realization spaces and tropical varieties
12:00-12:20 Uhr Lehrprobe zum Thema The Theorem of Carathéodory (auf Englisch) ca. 12:30-13:10 Uhr Fachvortrag: Polytopes meet polynomials: realization spaces and tropical varieties Many exciting research topics lie at the interface between discrete, tropical, and algebraic geometry. In this talk I will present examples of such topics based on some of my research projects. The first part introduces the study of algebraic degrees of realizations of polytopes satisfying some geometric constraints. The second one focuses on the analysis through the lens of tropical geometry of models of cubic surfaces, matroid polytopes, and their subdivisions. Throughout the talk, I will highlight how discrete and algebraic methods fruitfully interact and provide new insights and computational tools.
