10. Nearby motivic sheaves of weighted equivariant functions

Florian Ivorra (Université de Rennes 1)

Let X be a smooth algebraic variety (over a field of characteristic zero) endowed with a multiplicative action of the affine line. In a recent work with Julien Sebag we show that the nearby motivic sheaf functor of a weighted equivariant function on X commutes with direct images for twists (by some Thom equivalence) of constant motives. In this talk, I will sketch the proof of this result and...

18. Iwasawa modules along p-adic Lie extensions

This talk will define various modules that occur in Iwasawa theory over different p-adic Lie extensions and provide a survey of recent results and open conjectures.
