The Hochschild cohomology groups under gluing arrows
Published 16 Jul 2023 in math.KT | (2307.08057v2)
Abstract: In a previous paper arXiv:2211.05435 we have compared the Hochschild cohomology groups of finite dimensional monomial algebras under gluing two idempotents. In the present paper, we compare the Hochschild cohomology groups of finite dimensional monomial algebras under gluing two arrows.
