En-cohomology as functor cohomology and operations

Abstract. En-algebras, algebraic analogues of n-fold loop spaces, come with a suitable notion of cohomology, called En-cohomology. In this talk, I will explain how to interpret En-cohomology of a commutative algebra with coefficients in a symmetric bimodule as functor cohomology and discuss the Yoneda pairing in this context.
