Abstract :
We observe some new characterizations of n-presented modules. Using the concepts of (n; 0)-injectivity and (n; 0)-atness of modules, we also present some characterizations of right n-coherent rings, right n-hereditary rings, and right n-regular rings.
Keywords :
(n , 0) , injective modules, (n , 0) , at modules, n , coherent rings, n , hereditary rings n , regular rings.
