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…
Subrepresentations of Kronecker representations
Yang Han
Translated into the language of representations of quivers, a challenge in matrix pencil theory is to find sufficient and necessary conditions for a Kronecker representation to be…
Is tame open?
Yang Han
Is tame open? No answer so far. One may pose the Tame-Open Conjecture: Tame is open. But how to support it? No effective way to date. In this note, the rank of a wild algebra is in…
