### Geometric Group Theory at Infinity

In this 3-day-long event we will bring together experts in GGT and related areas from Great Britain and Germany, as well as members of the SPP interested in the subject.

### Augsburg-Fribourg-Karlsruhe Riemannian Topology Meeting

The Riemannian Topology Meeting (RTM) is an irregularly recurring activity addressing mathematicians interested in the interplay of algebraic and geometric topology with riemannian geometry. Its tradition reaches back to 2012 during which it took place at the universites of Fribourg, Karlsruhe and Göttingen.

This RTM, taking place at the University of Fribourg, focuses on fostering the mathematical intercommunication between the research groups in Augsburg, Fribourg and Karlsruhe, which are participating in the SPP 2026 DFG project.

### Geometric Singular Analysis and Mathematical Physics

During the conference at University Oldenburg we shall gather international experts as well as young researchers in the field of geometric analysis and mathematical physics with a focus on the following three mutually related topics

1. Spectral geometry of singular (and non-compact) spaces

2. Geometric flows and curvature problems on singular spaces

3. Geometric analysis and mathematical physics

#### 25/06/2018 | Seminar

### Blockseminar "Selberg'sche Spurformel"

Die Mathematik der riemannschen Flächen, speziell die derjenigen vom Geschlecht mind. 2, ist außerordentlich reichhaltig. Solche Flächen besitzen hyperbolische Strukturen, d.h. Metriken mit konstanter Krümmung -1.

Wir werden tiefe Zusammenhänge zwischen analytischen Größen (Laplace-Eigenwerte), geometrischen Größen (Längen geschlossener Geodätischer) und arithmetischen Aspekten erkunden. Ein Höhepunkt wird dabei die Selberg'sche Spurformel sein, in der diese Aspekte zusammenfließen.
