2 Mar – Two Mathematical Talks at the BMS Days 2021!

24.02.2021
On 1 and 2 March 2021, the Berlin Mathematical School will host its first online BMS Days. On Tuesday, 2 March 2021 all events will be open to the MATH+ community. We are pleased to invite you to attend the following two talks: Gabriele Steidl (TU Berlin) – Motion and Deformation in Mathematical Imaging (11:00 am); Gaëtan Borot (HU Berlin) – Matrix models and counting surfaces: from combinatorics...

19 Feb – Richard E. Schwartz: On the optimal paper Möbius band

09.02.2021
In this talk, Schwartz will explain the bounds proved by Halpern and Weaver and then show how to improve the lower bound. He will also explain an approach to getting the sharp bound, which amounts to approximating a paper Möbius band by certain kinds of finite tensegrities. Richard E. Schwartz got his Ph.D. in mathematics from Princeton University in 1991. He is currently the Chancellor Professor...

5 Feb – Sylvia Serfaty: Systems of points with Coulomb interactions

01.02.2021
Large ensembles of points with Coulomb interactions arise in various settings of condensed matter physics, classical and quantum mechanics, statistical mechanics, random matrices and even approximation theory, and they give rise to a variety of questions pertaining to analysis, partial differential equations and probability. Sylvia Serfaty is the Silver Professor of Mathematics at the Courant Ins...

22 Jan – Rolf Krause: Scales of knowledge

19.01.2021
Complex coupled systems arise in medicine, science and engineering. Mathematically, these can be nonlinear coupled systems of PDEs or the nonconvex minimization problems found in deep learning. In this talk, we show how multi-scale approaches give a mathematical technique for accurate and efficient simulation of complex systems. Rolf Krause holds a chair of advanced scientific computing in the Fa...

15 Jan – Harald Helfgott: Expander graphs in number theory: the prime divisibility graph

12.01.2021
An expander graph may be defined in any of several ways: in terms of boundaries of vertex sets, or in terms of eigenvalues of the graph Laplacian, or by random walks... Expander graphs have become a central object of study in discrete mathematics. Helfgott will discuss a graph that encodes the divisibility properties of integers by primes. Harald Helfgott is a Humboldt Professor at the University...
