Many exponential sums over finite fields, such as Gauss or
Salié-Kloosterman sums, appear as the Fourier-Melin transform of the
trace function of an l-adic sheaf on a commutative algebraic group. We are interested in the equidistribution of such sums as the character varies. Generalizing work by Deligne and Katz in the cases of additive and multiplicative groups, a Tannakian formalism always controls the
equidistribution. In this talk, I will illustrate this result in some concrete cases where the group is an abelian variety. This is a collaboration with Javier Fresán and Emmanuel
Kowalski.
