Titre The Hodge numbers of OG10 via Ngo strings I
Date19/09/2019
Horaire14:00 à 15:00
Résume

I will report on joint work with M. de Cataldo and A. Rapagnetta, in which we compute the Hodge numbers of the 10-dimensional hyperkähler manifold known as OG10. This is done by comparing the cohomology of OG10 with the cohomology of certain HK manifolds of K3^[n]-type, which is known. For this we use Ngô's support theorem applied to several Lagrangian abelian fibrations appearing naturally in the picture. In the first lecture I will give an overview of the arguments, while in the second one I will give more details.
