Self-injective Algebras and the Second Hochschild Cohomology Group

In this paper we study the second Hochschild cohomology group HH(Λ) of a finite dimensional algebra Λ. In particular, we determine HH(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(Λ) in the few cases where it is not zero.

Auslander Algebras of Self-Injective Nakayama Algebras

For the Auslander algebras E of self-injective Nakayama algebras, the Δ-filtrations of the submodules of indecomposable projective Emodules are determined, a class of Δ-filtered E-modules without selfextensions are constructed, and the Ringel dual of E is described. Mathematics Subject Classifications: 16G10

ON GRADED INJECTIVE DIMENSION

There are remarkable relations between the graded homological dimensions and the ordinary homological dimensions. In this paper, we study the injective dimension of a complex of graded modules and derive its some properties. In particular, we define the $^*$dualizing complex for a graded ring and investigate its consequences.

On Amenability of Group Algebras, Ii: Graded Algebras

We show that, in a finitely generated amenable group G with lower central series (γn(G)), the function n 7→ rank(γn(G)/γn+1(G)) grows subexponentially. This paper continues [22,2]’s study of amenability of affine algebras (based on the notion of almost-invariant finite-dimensional subspace), and applies it to graded algebras associated with finitely generated groups. We consider the graded defo...
