Relative Homological Theory On Co-absolutely Co-pure Modules

In this paper,we mainly discuss some relative homological modules basing on the notion of co-absolutely co-pure modules. Firstly,we define the notion of FCRP-injective modules. Then we induce the definitions of n-FCRP-injective modules,(d, n)-projective modules and (d, n)P-injective modules. And also we study their main properties.
