Weighted Generalized Inverses of Matrices over Integral Domains
Xiaoji Liu · Journal of Sichuan Normal University · 2009
In this article,weighted generalized Moore-Penrose inverses of Matrices over integral domains is defined and studied. Necessary and sufficient conditions for this kind of inverse to exist are given. By using a lemma of D. W. Robinson(Linear Algebra Appl.,2005,411:254-276) an expression of the generalized inverse is also given.
