Javed Hussain, Muhammad Shabir · European Journal of Pure and Applied Mathematics · 2018
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.
