COMMUTING MAPPS OF MODULE EXTENSION ALGEBRAS

sepideh ebrahimi

Abstract


We investigate the structure of commuting map on module extension alge-

bras. In particular, we give conditions that every commuting map L on such an algebra

is of the form L(c) = cx+h(c), where x lies in the center of the algebra and h is a linear

map from the algebra to its center.
