[PDF][PDF] On m-injective and m-projective modules
Y Alagöz - Mathematical Sciences and Applications E-Notes, 2020 - dergipark.org.tr
In this study, the concept of m-projective modules is introduced. A right R-module M is said
to be m-projective if Ext (M, N)= 0 for any m-injective right R-module N. We prove that every …
