ON GENERALIZED n-PRESENTED MODULES
摘要
Abstract
In this paper, we investigate the problem on computations of projective dimensions of modules and global dimensions of rings. Using the properties of n-presented modules, we obtain the structure theorem of generalized n-presented modules and the method to compute global dimensions of right n-coherent rings, which generalize the known ones.关键词
