  • From October 2020 to June 2021, I am in charge of the 24th Internetseminar (ISem24), together with Christian Budde, Xin Li and Christian Voigt. Since 1997, the Internetseminar has taken place every year, dedicated to some specific topic in functional analysis and evolution equations. In ISem24, we will introduce to C*-algebras and dynamics; we expect several hundreds of participants worldwide. Looking forward to it!

Heisenberg Programme

Since March 2021, Moritz Weber is a Heisenberg Professor for Mathematics at Saarland University. This is a five year professor position funded by the German Research Foundation (DFG). The title of the this five year project is Compact Matrix Quantum Groups of Combinatorial Type. The aim is to investigate the representation theory of combinatorial type quantum groups and to explore links with quantum information theory.


Symbolic Tools in Mathematics and their Application

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) has established the transregional collaborative research centre (SFB-TRR) 195 “Symbolic Tools in Mathematics and their Application” starting in January 2017.  Host university is the University of Kaiserslautern (TU Kaiserslautern), additional applicant universities are RWTH Aachen University and Saarland University.

What are quantum symmetries?

In mathematics, symmetries are usually captured by the formalism of groups. However, in the realm of ``quantum mathematics'', certain noncommutative algebraic structures arise and we need to go beyond groups in order to describe its symmetries: we need to consider quantum groups. There is a short Oberwolfach Snapshot gently introducing to quantum symmetry.
