Topic: 

A Satake homomorphism for the mod p derived Hecke algebra

Description: 

Recently, Venkatesh introduced a global version of the derived Hecke algebra to explain extra endomorphisms on the cohomology of arithmetic manifolds: the crucial local construction is a derived version of the spherical Hecke algebra of a reductive p-adic group.
Working with p-torsion coefficients, we will describe a Satake homomorphism for the derived spherical Hecke algebra of a p-adic group. This allows us to understand its structure well enough to attack some global questions, which are work in progress.
