International Seminar on Automorphic Forms

Fu-Tsun Wei (National Tsing Hua University)

In this talk, I will first determine the algebraic relations among various special gamma values over function fields. The result is based on the intrinsic relations between gamma values in question and periods of CM dual t-motives, which are interpreted in terms of their “distributions”. This enables us to express every “abelian” CM period by a suitable product of special gamma values (up to an algebraic multiple), and derive a Chowla–Selberg-type formula in the function field case.
