Modules with respect to cyclic purity
L Mao - Mathematica Scandinavica, 2011 - JSTOR
An exact sequence 0→ A→ B→ C→ 0 of left R-modules is called cyclically pure if for every
right ideal I of R, the sequence 0→(R/I)⊗ A→(R/I)⊗ B→(R/I)⊗ C→ 0 is exact. In this paper,
we study some special modules with respect to cyclic purity, such as CP-projective, CP-
injective and CP-flat modules.
