Comparing the simplicial and the hochschild cohomologies of a finite dimensional algebra

Autor: J. A. de la Peña, Ma. I. R. Martins

Publikováno v: Journal of Pure and Applied Algebra. 138:45-58

Let A be a finite dimensional, basic algebra over an algebraically closed field k. We compare the Hochschild cohomology group Hi(A) = Hi(A, A) with the simplicial cohomology groups SHi(A, Z) defined in [6] for any abelian group Z. We show that SH1 (A
