On the Mumford-Tate conjecture for products of abelian varieties

A talk in the 'Bielefeld Arithmetic Geometry Seminar' series by
Johan Commelin from Utrecht
Abstract: The Mumford-Tate conjecture relates the Hodge structure on the singular cohomology of an algebraic variety (over a number field) with the Galois representation on the etale cohomology of that variety. In this talk I will report on techniques for proving the Mumford-Tate conjecture for products of abelian varieties, under the assumption that the conjecture is known for the factors.
