Let R be a commutative Noetherian ring. Let P(R) (respectively, I(R)) be the category of all finite R-modules of finite projective (respectively, injective) dimension. Sharp [9] constructed a category equivalence between I(R) and P(R) for certain CohenMacaulay local rings R. Thus many properties about finite modules of finite projective dimension can be connected with those of finite injective dimension through this equivalence.
