The Discussion Of Questions Related To Ding Homological Dimensions

On the discussion of the Ding homological dimension of modules are investigat-ed in this paper.Firstly,we present an alternative way of measuring the Ding ho-mological dimension of modules via a widespread of complete projective(injective)resolutions,and discuss the relationship between the generalized Ding projective(injective)module and the module of finite Ding projective(injective)dimension.Secondly,we discuss the structure of Ding projective modules and Ding projective dimension of modules over formal triangular matrix ring.At last,we investigate the property of W-Gorenstein flat.modules.
