SUMMARY:Séminaire TNGA : Arnab Kundu
DESCRIPTION:Orateur : Arnab Kundu (Institutul de Matematică « Simion Stoilow ») \n\n\n\nTitre : Purity of Motivic Cohomology in mixed-characteristic \n\n\n\nRésumé : Motivic cohomology is a cohomology theory that can be defined internally within Grothendieck’s category of motives. Voevodsky developed this theory for smooth varieties\, demonstrating its profound connections to algebraic cycles and algebraic K-theory. However\, its behaviour in mixed-characteristic remains less well understood. Building on recent advancements by Bachmann\, Elmanto\, Morrow\, and Bouis\, in a joint work with Bouis\, we demonstrate a purity result over deeply-ramified bases. I will also discuss an application of this result in p-adic Hodge theory.
