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 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…
