On a new construction of Nori motives

by Prof. Pierre CARTIER (CNRS & IHES)

mercredi 18 mai 2016 de au (Europe/Paris)
at IHES ( Amphithéâtre Léon Motchane )
Le Bois Marie 35, route de Chartres 91440 Bures-sur-Yvette
Description

I shall report about a new direct construction of Nori motives, discovered independently by Barbieri-Viale and Prest on the one hand, by Joyal and myself on the other hand. Unlike previous constructions, one uses only standard constructions in category theory, like Frey free abelian category on a given additive category, and Serre’s construction of quotient categories.
