Zero action determined modules for associative algebras

Rings and Algebras 2017-07-31 v1

Abstract

Let AA be a unital associative algebra over a field FF and VV be a unital left AA-module. The module VV is called zero action determined if every bilinear map f:A×VFf: A\times V\rightarrow F with the property that f(a,m)=0f(a,m)=0 whenever am=0am=0 is of the form f(x,v)=Φ(xv)f(x,v)=\Phi(xv) for some linear map Φ:VF\Phi: V\rightarrow F. In this paper, we classify the finite dimensional irreducible and principal projective zero action determined modules of AA. As an application, two classes of zero product determined algebras are shown: some semiperfect algebras (infinite dimensional in general); quasi-hereditary cellular algebras.
