| Abstract: | Let R be a local ring with 2 is an unit.In this paper,the inclusion relation of the generalized inverse of linear combinations of three nonzero n times n idempotent matrices which are mutually commutative are studied over a local ring R,and the tabulation algorithm for the generalized inverse of a class special matrix are given.Moreover,by using the tabulation algorithm and the relative matrix theory,the necessary and sufficient conditions of inclusion relationships about the generalized inverse of linear combinations of these matrices are obtained,and the relative theory of reverse order law for reflexive generalized inverse of matrix are also generalized. |
