    • Rings For Which Every Cosingular Module Is Projective 

      Talebi, Y.; Hamzekolaee, A. R. M.; Hosseinpour, M.; Harmanci, A.; Ungor, B. (2019)
      Let R be a ring and M be an R-module. In this paper we investigate modules M such that every (simple) cosingular R-module is M-projective. We prove that every simple cosingular module is M-projective if and only if for N ...
