Shimura varieties with ${\Gamma }_1(p)$-level via Hecke algebra isomorphisms: the Drinfeld case

T. Haines, M. Rapoport

We study the local factor at p of the semi-simple zeta function of a Shimura variety of Drinfeld type for a level structure given at p by the pro-unipotent radical of an Iwahori su…
