Colloquium: Tuesday, March 29, 2 pm. Speaker: Omer Offen (Technion) . Title: “Period integrals of automorphic forms: A tour via examples old and new”.

Fourier coefficients of classical modular forms are related to classical problems in number theory such as Fermat’s sum of two squares theorem.
In turn, in modern language, they are special examples of period integrals of automorphic forms. I intend to introduce the notation of period integrals, with emphasis on examples and applications.
I will avoid the general theory of automorphic forms.
