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 right R-module has a special m-projective precover and
m-injective preenvelope. We characterize C-rings, SF-rings and max-hereditary
rings using m-projective and m-injective modules.
