## Activities of SPP2026

On this site you find all conferences, workshops and seminars that have been or will be (financially and organisationally) supported by the DFG priority programme „Geometry at Infinity“.

#### 03/09/2018 | Workshop

### Ricci flow, mean curvature flow and related singular flows

This 4-day workshop is addressed to graduate students and researchers in geometric analysis and differential geometry. It will mainly focus on geometric flows on smooth and singular manifolds and related topics such as Ricci solitons.

### 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.

### Analysis and Geometry on Graphs and Manifolds

The aim of this conference is to bring people together from geometry, operator theory, partial die l equations, probability and combinatorics. A particular focus lies on the connection between a discrete and a continuum viewpoint on the nature of the underlying space.
