C-PURE SUBMODULES AND C-FLAT MODULES
Y Alagöz - Journal of Universal Mathematics, 2021 - dergipark.org.tr
Let R be a ring. A right R-module A is said to be C-flat if the kernel of any epimorphism B→ A
is C-pure in B, ie the induced map Hom (C, B)→ Hom (C, A) is surjective for any cyclic right …

Relative FP-Projective Modules
L Mao, N Ding - Communications in Algebra, 2005 - Taylor & Francis
Let R be a ring and M a right R-module. M is called n-FP-projective if Ext 1 (M, N)= 0 for any
right R-module N of FP-injective dimension≤ n, where n is a nonnegative integer or n=∞. ν …
