Hochschild cohomology of truncated quiver algebras
Yunge Xu, Yang Han, Wenfeng Jiang
For a truncated quiver algebra over a field of arbitrary characteristic, its Hochschild cohomology is calculated. Moreover, it is shown that its Hochschild cohomology algebra is fi…

Hochschild (co)homology of exterior algebras
Yang Han, Yunge Xu
The minimal projective bimodule resolutions of the exterior algebras are explicitly constructed. They are applied to calculate the Hochschild (co)homology of the exterior algebras.…

Hochschild (co)homology dimension
Yang Han
In 1989 Happel conjectured that for a finite-dimensional algebra over an algebraically closed field , $\gl A< \infty$ if and only if $\hch A < \infty$. Recently Buchweitz-Gr…
