Simon Cooper: Tautological rings of Shimura varieties

Tid: On 2021-02-24 kl 13.15 - 14.15

Föreläsare: Simon Cooper, Stockholms universitet

Plats: Zoom, meeting ID: 685 0671 8075

Abstract 

I will discuss tautological rings of Shimura varieties of Hodge-type following Wedhorn-Ziegler. For toroidal compactifications these rings are described purely in terms of group theoretic data by W-Z. I shall instead focus on the non-compact case, which requires certain geometric input from the boundary. I will do this for Hilbert modular varieties in positive characteristic, generalising the methods used by Van de Geer in the case of the moduli of abelian varieties \(A_{g}\).
