| Jul 7, 2017 at 17:59 | comment | added | darij grinberg | Actually, maybe this helps: Guillermo Ames, Leandro Cagliero, Paulo Tirao, The GL-module structure of the Hochschild homology of truncated tensor algebras. The algebra they study is the same; but they study the homology, not the cohomology. But the projective resolution can't hurt... | |
| Jul 7, 2017 at 17:57 | comment | added | darij grinberg | @Mare: Oops, I got the module wrong. Sorry, but can you please change the title to something more concrete than just "Hochschild cohomology" (this is a tag on 61 questions)? | |

| Jul 7, 2017 at 16:36 | comment | added | Victor Protsak | You probably mean that $J$ is the ideal generated by $x_1,\dots,x_n$ (the span of these elemens is not an ideal). | |
| Jul 7, 2017 at 15:13 | comment | added | Mare | I think the new title does not fit to the problem. | |

| Jul 7, 2017 at 8:34 | comment | added | Julian Kuelshammer | For the commutative case, the Hochschild cohomology ring should be the polynomial ring in $n$ variables over $A$ for $m=2$ and for $m>2$ it should be the tenor product over $A$ of an exterior algebra in $n$ variables over $A$ and a polynomial ring in $n$ variables over $A$. For $n=\operatorname{char} K$ this is stated in "Hopf algebra structures and tensor products of group algebras" by Carlson and Iyengar. | |
