On M-Principally Injective and Projective S-acts
Abstract
In this paper, we have introduced the notions of M-cyclic S-acts,
M-principally projective and injective S-acts, semi-projective S-acts and co-
cyclic S-acts, whereMis a right S-act. Several interesting properties, charac-
terizations relations between newly dened structures have been investigated.
