Fengxia Zhang · Journal of Lanzhou University of Technology · 2012
The relation between {1,3}-inverse and {1,4}-inverse of sum of two matrices and the sum of {1,3}-inverse and {1,4}-inverse of every matrix was studied by using matrix rank method and maximal ranks and minimal ranks of generalized Schur complement.The necessary and sufficient conditions of {A(1,3)+B(1,3)}={(A+B)(1,3)} and {A(1,4)+B(1,4)}={(A+B)(1,4)} were obtained.
