MP-dimension of a meta-projective duo-ringKeywords: Duo-ring , meta-projective module , projective module , reflexive module , MP-dimension Abstract: We extend the MP-dimension notion to the meta-projective duorings.In Theorem 5.5 and Theorem 5.7, we make use of this notion togive sufficient conditions on commutative noetherian rings to be artiniansemi-simple. Some results on artinian rings are discussed.
