2114 - Arbeitsgemeinschaft: Derived Galois Deformation Rings and Cohomology of Arithmetic Groups (hybrid meeting)

[OWR-2021-18] Workshop Report 2021,18 (2021) - (04 Apr - 10 Apr 2021)

The purpose of the workshop was to study derived generalizations of Mazur's deformation ring of Galois representations, and the relationship of such a derived deformation ring to the homology of arithmetic groups.
2141 - Arbeitsgemeinschaft: Thin Groups and Super-approximation (hybrid meeting)

[OWR-2021-50] Workshop Report 2021,50 (2021) - (10 Oct - 15 Oct 2021)

The aim of this workshop was to discuss the super-approximation of thin groups, its dynamical implications in terms of the mixing of geodesic flows, and applications to various problems in arithmetic, geometry, and dynamics.
2110a - Homotopic and Geometric Galois Theory (online meeting)

[OWR-2021-12] Workshop Report 2021,12 (2021) - (07 Mar - 13 Mar 2021)

In his "Letter to Faltings'', Grothendieck lays the foundation of what will become part of his multi-faceted legacy to arithmetic geometry. This includes the following three branches discussed in the workshop: the arithmetic ...
2105 - Moduli spaces and Modular forms (hybrid meeting)

[OWR-2021-6] Workshop Report 2021,6 (2021) - (31 Jan - 06 Feb 2021)

The relation between moduli spaces and modular forms goes back to the theory of elliptic curves. On the one hand both topics experience their own growth and development, but from time to time new unexpected links show ...
