Hochschild cohomology of algebras with homological ideals
C Xi - Tsukuba journal of mathematics, 2006 - projecteuclid.org
Let $\varphi: A\to B $ be a homological epimorphism of $ k $-algebras. We investigate the
relationship of the Hochschild cohomologies $ H^{i}(A) $ and $ H^{i}(B) $ of $ A $ and $ B …

On the first Hochschild cohomology group of a cluster-tilted algebra
Given a cluster-tilted algebra B, we study its first Hochschild cohomology group HH 1 (B)
with coefficients in the BB-bimodule B. If C is a tilted algebra such that B is the relation …

Coverings of laura algebras: the standard case
I Assem, JC Bustamante, P Le Meur - Journal of Algebra, 2010 - Elsevier
In this paper, we study the covering theory of laura algebras. We prove that if a connected
laura algebra is standard (that is, has a standard connecting component), then it has Galois …
