The Second Hochschild Cohomology Group for One-Parametric Self-Injective Algebras ()
Abstract
In this paper, we determine
the second Hochschild cohomology group for a class of self-injective algebras
of tame representation type namely, which are standard one-parametric but not
weakly symmetric. These were classified up to derived equivalence by Bocian,
Holm and Skowroński in [1]. We connect this to the deformation of these
algebras.
