| dc.description | In this paper we study the second Hochschild cohomology group ${HH}^2(Λ)$ of a finite dimensional algebra $Λ$. In particular, we determine ${HH}^2(Λ)$ where $Λ$ is a finite dimensional self-injective algebra of finite representation type over an algebraically closed field $K$ and show that this group is zero for most such $Λ$; we give a basis for ${HH}^2(Λ)$ in the few cases where it is not zero. | |
