Title: The ordinary quivers of Hochschild extension algebras for self-injective Nakayama algebras
Abstract: Let $T$ be a Hochschild extension algebra of a finite dimensional algebra $A$
over an algebraically closed field K by the standard duality $A$-bimodule ${\rm Hom}_K(A,\,K)$.
In this talk, we determine the ordinary quiver of $T$ if $A$ is a self-injective Nakayama algebra
by means of the $\mathbb{N}$-graded second Hochschild homology group $HH_2(A)$ in the sense of Sk\oldberg.
