We will discuss edge random subgraphs of finite graphs, focusing on their typical behavior (component sizes, properties of the giant component, and such) below and above the critical edge probability. Results for some concrete classical models, such as the binomial random graph G(n,p) and the random subgraph of the high-dimensional hypercube Q^d, as well as general theorems for d-regular base graphs will be presented.

Summer Semester 2022

A probabilistic approach to the convergence of large population games to mean field games

Jul 6, 2022 @ TU (room 043) - 17:15

Mean field games are infinite population idealizations of Nash equilibrium problems in symmetric, finite population games in the microscopic regime. They present enormous advantages, and their study has given rise to an imporant literature over the past decade with striking applications. 

This talk is the opening for a mini-series and will be followed by two in-depth presentations on strong and weak formulations for such games and applications.

Jul 7, 2022 @ HU (room 1'115) - 16:30

This talk will discuss the convergence problem of mean field games in the strong formulation. The specific example of a price impact model will be presented. If time allows it, an application to stochastic optimal transport will be discussed to showcase the relevance of the method beyond mean field games.

Jul 7, 2022 @ HU (room 1'115) - 17:45

This talk will discuss the convergence problem of mean field games in the weak formulation. A specific case study will be discussed. Time permitting, we will finish with an outlook on the case of players in non-symmetric interaction.

Coming from AIMS South Africa, Ludovic Tangpi started his doctorate as a BMS student at HU Berlin under direction of Michael Kupper, before following his supervisor to Konstanz. After postdoc positions in Konstanz and Vienna, he is now Assistant Professor at Princeton University. His visit to the stochastics group at HU is enabled through the Berlin-AIMS Network in Stochastic Analysis in the DAAD program for cooperations with AIMS.


Winter Semester 2020/21

Multilevel Strategies for Non-Linear Problems and Machine Learning: On Non-Linear Preconditioning, Multilevel Optimization, and Multilevel Training.

Jan 5, 2021 15:00
Jan 7, 2021 15:00
Jan 12, 2021 15:00
Jan 14, 2021 15:00

In this lecture series, we will discuss the main ideas of multilevel optimization techniques and their relation to classical multigrid theory. We will discuss how multilevel optimization methods for convex and non-convex minimization problems can be constructed and analyzed. We will study the significant gain in convergence speed, which can be achieved by multilevel minimization techniques.

Multilevel optimization techniques are also intimately linked to non-linear preconditioning. As it turns out, the minimization-based view on non-linear problems can not only help to design efficient preconditioners, but is also useful for the construction of globalization strategies.

In the last part of the lecture series, we will employ multilevel optimization techniques in the context of machine learning and will discuss their benefits for the training of neural networks. Various numerical examples from phase field models for fracture, from non-linear elasticity, cardiac simulation, and from deep learning will illustrate our findings.“

Rationality of algebraic varieties with an emphasis on cubics
Each Tuesday from 09:30 (s.t.) in the BMS Seminar Room 1.023 in the HU Math Department in Adlershof. 
First meeting: Tuesday, 23 October 2018. 

The course aims to study rationality of algebraic varieties with am emphasis on cubic hypersurfaces from the point of view of complex projective algebraic geometry. Elementary and basic tools will be constructed to address the geometry of these varieties and some important related topics in dimension 3 and 4. Here is a list of the topics to be covered: 

I. Basic algebraic geometry of cubic hypersurfaces. The polar linear system of quadrics, the Hessian, the Fano variety of lines. Special examples of cubics. Cubics with many nodes. 

II. Historical perspective on rationality problems. Cubic threefolds: intermediate Jacobian. Clemens-Griffiths theory. Methods to prove irrationality. Quartic double solids: Voisin’s recent results of non stable rationality. 

III. Cubic fourfolds. Examples of rational cubic fourfolds. Conjecturally rational cubic four- folds and K3 surfaces. Families of cubic fourfolds whose Fano variety of lines is the Hilbert scheme of two points of a K3. Enumerative geometry of nodal rational scrolls for special cubic fourfolds. Moduli of polarized K3 surfaces and cubic fourfolds.
