Rigidity of higher Auslander algebras of type
Sibylle Schroll, Andrea Solotar, Can Wen
We show that the Hochschild cohomology of higher Auslander algebras of type vanishes in all positive degrees and is one-dimensional in degree zero. As a consequence, t…
Hochschild cohomology of graded skew-gentle algebras: Gerstenhaber algebra structure and geometric interpretation
Xiuli Bian, Sibylle Schroll, Andrea Solotar +2
In this paper we calculate the Hochschild cohomology of graded skew-gentle algebras, together with its structure as graded commutative algebra under the cup product and its Lie alg…
The Hochschild cohomology groups under gluing arrows
Yuming Liu, Lleonard Rubio y Degrassi, Can Wen
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, w…
On the first Hochschild cohomology of finite dimensional quiver algebras under gluing idempotents
Yuming Liu, Lleonard Rubio y Degrassi, Can Wen
We compare the Lie algebra structures of the first Hochschild cohomology groups of a quiver algebra and a radical embedding obtained by gluing two idempotents of . Under…
