9 February – Amandine Véber: A stochastic model for the growth of a filamentous fungus (Kovalevskaya Colloquium)

The last MATH+ Friday of the winter semester 2023/24 is a Kovalevskaya Colloquium. This talk will present a toy model for the development of a hyphal network, whose main aim is to identify a small number of key parameters describing the growth of the fungus in homogeneous conditions (in particular, in lab conditions) and to understand and quantify the impact of different forms of stress on this gr...

26 January – Thomas Nikolaus: The K-Theory of Z/n

Thomas Nikolaus will indicate how modern tools (such as prismatic cohomology, p-adic Hodge theory, higher algebra) make it possible to tackle fundamental computations, such as K-Theory of finite rings, which have remained open since the 1970s. Thomas Nikolaus is professor of mathematics at the University of Münster.

12 January – Diane Maclagan: Tropical geometry

Maclagan will give a gentle introduction to this twenty-first century field, giving some idea of where it can be applied, both inside and outside algebraic geometry. Diane Maclagan is a Professor of Mathematics at the University of Warwick in the United Kingdom.

15 December – Ailsa Keating: The symplectic topology of singularities

Given an isolated complex singularity, any smoothing (i.e. Milnor fibre) of it is naturally a symplectic manifold. This leads to a rich interplay, first suggested by Arnol’d. Ailsa Keating works on problems in symplectic geometry and homological mirror symmetry. In the summer of 2023, she moved to the University of Vienna.

1 December – Start of the MATH+ Advent Calendar 2023

While others hiding chocolates, the MATH+ Advent Calendar (in English and German) is challenging you with mathematical brainteasers! The 24 challenges of the MATH+ Advent Calendar invite you to dive into MATH+ research projects. Join in and have fun!

1 December – Andreas Thom: Equations over groups

The study of equations in the language of groups has a long history and many applications. Thom will explain how topological methods can be applied to solve equations over groups and also mention some recent advances in the study of identities for finite and infinite groups. Andreas Thom is full professor of geometry at TU Dresden.
