One can view the affine Hecke category of equivariant coherent sheaves on the Steinberg variety as a "matrix algebra" over the adjoint quotient of a reductive group. Thus one expects its center and abelianization (Hochschild cohomology and homology categories) to involve equivariant coherent sheaves on the commuting variety. We will present precise descriptions involving coherent sheaves with prescribed singular support. This is joint work with D. Ben-Zvi (Texas) and A. Preygel (Berkeley).
