In this note, we introduce S-semi commutative, S-Baer, S-q.-Baer and S-p.q.-Baer modules. We study the relations between these classes of modules. Also we prove if M is an S-semicommutative module, then M is an S-p.q.-Baer module if and only if M[x] is an S[x]-p.q.-Baer module, M is an S-Baer module if and only if M[x] is an S[x]-Baer module, M is an S-q.-Baer module if and only if M[x] is an S[x]-q.-Baer module.eninfo:eu-repo/semantics/closedAccessBaer ModulesPrincipally Quasi-Baer ModulesQuasi-Baer ModulesSemicommutative ModulesArticle10.1007/s12044-009-0015-211921491582-s2.0-67650257719Q3WOS:000268237300003Q4
