Title: Universal norms of p-adic Galois representations.
Abstract: I will talk about the problem of universal norms which naturally appears in Iwasawa theory, notably to establish "control theorems" for Selmer groups. This problem was first studied by Mazur in his fundational work on Iwasawa theory for abelian varieties. In 1996, Coates and Greenberg solved the problem for abelian varieties, but it remains open for general motives.
