Hossein Movasati donnera un mini-cours autour la théorie de Hodge destiné aux doctorant et autres curieux, dont le premier exposé sera mardi 14 juin 2022 à 10h30.

Title: Five lectures in Hodge Theory

Abstract:
The origin of Hodge theory goes back to many works on elliptic, abelian
and multiple integrals. In this lecture series I am going to explain how Lefschetz
was puzzled with the computation of Picard rank and this led him to consider
the homology classes of curves inside surfaces. This was ultimately formulated
in Lefschetz (1,1) theorem and then the Hodge conjecture which is one of the
millennium problems of Clay Mathematical Institute. The Hodge theory of
hypersurfaces and in particular Fermat varieties is emphasized.

The lectures are based on the books which are available in my webpage.
