Fields of interest:
(1) Special values of automorphic L-functions: The Deligne conjecture predicts the special values of L-functions at critical points. In our work we deal with the analogou of Deligne's conjecture for Automorphic L-functions. (2) P-adic families of automorphic forms: The Mazur-Gouvea Conjecture roughly asserts that any modular form fits into a p-adic analytic family of modular forms. In the case of ordinary forms this is Hida's theory, in general it has been proven by Coleman. In our work we want to introduce a new approach to the theory which is based on the trace formula.
