Abstract
Let be a monomial associative finite dimensional algebra over a field of characteristic zero. It is well known that the Hochschild cohomology of can be computed using Bardzell's complex . The aim of this article is to describe an explict -structure on that induces a weak equivalence of -algebras between and the Hochschild complex of . This allows us to describe the Maurer-Cartan equation in terms of elements of degree in . Finally, we make concrete computations when is a truncated algebra, and we prove that Bardzell's complex for radical square zero algebras is in fact a dg-Lie algebra.
