Abstract: We compute the Hochschild cohomology algebra of $GL_2$ over an algebraically closed field of characteristic $p>2$.
In this paper we construct a graded Lie algebra on the space of cochains on a Z2-graded vector space V = V0 ⊕ V1 that are skew-symmetric on the subspace V1. The Lie bracket is obtained from the classi...
We show that for any block algebra B of a finite group over an algebraically closed field
of prime characteristic p the dimension of HHn(B) is bounded by a function depending only
on the nonnegative...

A spectral sequence for the computation of the Hochschild cohomology of a coconnective dga over a field is presented. This spectral sequence has a similar flavour to the spectral sequence constructed ...
