243086 Rigid meromorphic cocycles (S) (WiSe 2021/2022)

Short comment

A rigid meromorphic cocycle is a class in the first cohomology of the discrete group SL2(Z[1/p]) with values in the multiplicative group of nonzero rigid meromorphic functions on Drinfeld's p-adic upper half-plane. It turns out that such objects play a crucial role to the class field theory for real quadratic fields. The purpose of this seminar is the study of the fundamental for this topic paper ``Singular moduli for real quadratic fields: A rigid analytic approach" by Henri Darmon and Jan Vonk.
