Small PPQ-injective Modules

S. Wongwai, O. Sthityanak

Abstract


Let   M be a right R − module.  A right R − module N is called  small pseudo principally  M − injective  (briefly,  small  PP − M − injective) if, every R − monomorphism from a   small and principal submodule of  M  to N can be extended to an R − homomorphism from M to N .  In this paper, we give some characterizations and properties of small PP − Q − injective modules.


Keywords
