A categorical Kunneth formula for Weil sheaves

Abstract: Drinfeld’s lemma measures the failure of the Kunneth formula for the etale fundamental group in positive characteristic $p > 0$ in terms of equivariance data under partial Frobenii. In the talk, I explain a sheaf-theoretic formulation for derived categories of lisse and constructible Weil sheaves on schemes. This is joint work in progress with Tamir Hemo and Jakob Scholbach.
