On the Lie algebra structure of the first Hochschild cohomology of gentle algebras and Brauer graph algebras

C Chaparro, S Schroll, A Solotar - Journal of Algebra, 2020 - Elsevier
In this paper we determine the first Hochschild homology and cohomology with different
coefficients for gentle algebras and we give a geometrical interpretation of these (co) …

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

I Assem, MJ Redondo, R Schiffler - Algebras and Representation Theory, 2015 - Springer
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 …

The Lie algebra structure of the first Hochschild cohomology group for monomial algebras

C Strametz - Comptes Rendus Mathematique, 2002 - Elsevier
We study the Lie algebra structure of the first Hochschild cohomology group of a finite
dimensional monomial algebra Λ, in terms of the combinatorics of its quiver, in any …

On the first -tilting Hochschild cohomology of an algebra

C Cibils, M Lanzilotta, EN Marcos, A Solotar - arXiv preprint arXiv …, 2024 - arxiv.org
In this paper we introduce, according to one of the main ideas of $\tau $-tilting theory, the
$\tau $-tilting Hochschild cohomology in degree one of a finite dimensional $ k $-algebra …

The first cohomology group of trivial extensions of special biserial algebras

Y Xu - Science in China Series A: Mathematics, 2004 - Springer
Given a finite dimensional special biserial algebra A with normed basis we obtain the
dimension formulae of the first Hochschild homology groups of A and the vector space Alt …

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 …

The first cohomology group of the trivial extension of a monomial algebra

C Cibils, MJ Redondo, M Saorin - arXiv preprint math/0210284, 2002 - arxiv.org
Given a finite--dimensional monomial algebra $ A $ we consider the trivial extension $ TA $
and provide formulae, depending on the characteristic of the field, for the dimensions of the …
