Zusammenfassung

Hilbert modular cusp forms of parallel weight two only show up in the middle degree cohomology of the appropiate locally symmetric space, whereas the analogous automorphic forms over number fields of arbitrary sign (e.g. Bianchi modular forms) show up in several degrees. It is an interesting question whether these cohomology groups all carry the same information. In this talk I give a partial answer to this question in the case of so-called automorphic L-invariants. These are certain p-adic periods one can attach to each cohomology group. I show that Venkatesh's conjectures on derived Hecke algebras implies a precise relationship between these L-invariants.



Nach dem Vortrag findet ein gemeinsamer Kaffee/Tee statt.
