Abstract

It is shown that the nondegeneracy of the Yoneda product (formula ommited) (M is either a noetherian module or a complex of finite projective dimension, and k is the residue field) characterizes the regularity of the ring A, whereas the isomorphism (formula ommited) characterizes the fact that A is Gorenstein.
