Talk
Nearby motivic sheaves of weighted equivariant functions
Talk by Prof. Dr. Florian Ivorra
Date: 20.12.21 Time: 13.15 - 15.00 Room:
(Joint work with Julien Sebag) Let X be a smooth variety (over a field of characteristic zero) endowed with a multiplicative action of the affine line. In this talk, I will prove that the nearby motivic sheaf functor of a weighted equivariant function on X commutes with direct images. I will also explain how this result provides a generalised functorial version of conjectures by Behrend-Bryan-Szendrői and Davison-Meinhardt that holds in the stable homotopy category of schemes. As a direct numerical consequence, we obtain a positive answer to the original conjectures of Behrend-Bryan-Szendrői and Davison-Meinhardt for virtual motives. <\br>
