#### 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.
