A Characterization of the Generalized InverseAT,S（2） over Integral Domains
Abstract：If A is an invertible matrix of order n over an integral domain, the inverse of A is the uniquematrix X such that p（I^A X^I）.In this paper, we generalize this fact to any general matrix over anintegral domain which is projective free to obtain an analogous result for the generalized inverse AT,S（2）.
