ABSTRACT: We will continue the Hochschild reading seminar with a recollection of the classical deformation theory of associative algebras and its relationship to Hochschild cohomology. There is a parallel story for cyclic cohomology which we will also discuss. This parallel story will motivate us to calculate the \(S^1\) equivariant homology of the configuration spaces of points in the plane.
