# Mathematics Münster

### Dynamics - Geometry - Structure

Mathematics is a key technology for scientific and economic progress. New discoveries in mathematics are not only interesting in themselves, but they often lead to unexpected breakthroughs in other sciences as well.

We will tackle fundamentally important mathematical problems, viewing mathematics as an organic whole with countless interactions. The research in our Cluster of Excellence "Mathematics Münster" is unified by three major approaches: focusing on the underlying structure of a given problem, taking the geometric viewpoint and studying the relevant dynamics of group or semigroup actions. The theories which we will build will not only solve the problems under consideration but also many others of a similar nature; these theories will also raise exciting new questions.

## Workshop Curvature and Global Shape

1 - 7 August 2021

The purpose of the meeting is to study relationships between local and global invariants in Riemannian Geometry. Our intention is to bring together experts in the field as well as young mathematicians. The programme of the Workshop is structured so that beyond the lectures there will be many opportunities for intensive discussions.

## Young Mathematicians in C*-Algebras

2 - 13 August 2021

YMC*A is an annual conference organised for and by master/PhD students and postdocs in operator algebras and related areas, with the goal of fostering scientific and social interaction between young researchers. YMC*A 2021 will take place in Münster in a hybrid format with online participation over Zoom and a limited number of participants present in Münster.

## Making optimal use of research data

WWU Münster is a partner of the "Mathematical Research Data Initiative" (MaRDI). MaRDI aims to enable the sustainable utilisation of mathematical research data. The consortium includes 25 partners (universities and research institutes, science infrastructure institutions, clusters of excellence as well as the German Mathematical Society DMV, and the European Mathematical Society EMS). It is coordinated by the Weierstrass Institute for Applied Analysis and Stochastics (WIAS) in Berlin. MaRDI will be funded as a consortium over a period of 5 years as of October 2021.

## Quanta Magazine reports on Infinity Proof

In May David Asperó and Ralf Schindler published their proof on a question from the 1990s about the relationship of two prominent axioms of set theory which both decide how many real numbers there are. Now Natalie Wolchover reports for the Quanta Magazine on the proof, its relevance and history.

## New Münster Research Fellow: Kilian Raschel

Dr. Kilian Raschel (CNRS, Université de Tours and Université d'Orléans) joins our Cluster as a Münster Research Fellow from 7 to 31 July 2021. He works on the connections between combinatorics and probability, a principal topic being random walks in cones seen from a combinatorial and a probabilistic point of view.

## New Young Research Fellow: Martin Holler

Ass.-Prof. Dr. Martin Holler (University of Graz) will join our Cluster as Young Research Fellow from 9 July to 9 August 2021. His field of research is the mathematics of inverse problems and data science. "I am looking forward to the excellent research environment in Münster and to a productive time", says Martin Holler.
