Résumé
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.
