max-projective modules
Abstract
A right -module is called max-projective provided that each homomorphism where is any maximal right ideal, factors through the canonical projection . We call a ring right almost- (resp. right max-) if every injective right -module is -projective (resp. max-projective). This paper attempts to understand the class of right almost- (resp. right max-) rings. Among other results, we prove that a right Hereditary right Noetherian ring is right almost- if and only if is right max- if and only if , where is semisimple Artinian and is right small. A right Hereditary ring is max- if and only if every injective simple right -module is projective. Furthermore, a commutative Noetherian ring is almost- if and only if is max- if and only if , where is and is a small ring.
