- 3:00 PM - 3:50 PM
- C304 Wells Hall
In this talk I will explain what Massey products are and focus on the vanishing conjecture due to Minac and Tan. I will survey the known results and the different methods used to obtain them, focusing on triple Massey products.

We introduce a derived enhancement of local Galois deformation rings that we call the “spectral Hecke algebra”, in analogy to a construction in the Geometric Langlands program. This is a Hecke algebra that acts on the spectral side of the Langlands correspondence, i.e. on moduli spaces of Galois representations. We verify the simplest form of derived local-global compatibility between the action of the spectral Hecke algebra on the derived Galois deformation ring of Galatius-Venkatesh, and the action of Venkatesh’s derived Hecke algebra on the cohomology of arithmetic groups.
