Towards finding equalities involving mixed products of the Moore-Penrose and group inverses by matrix rank methodology
Given a square matrix AA, we are able to construct numerous equalities involving reasonable mixed operations of AA and its conjugate transpose A∗{A}^{\ast }, Moore-Penrose inverse A†{A}^{\dagger } and group inverse A#{A}^{\#}. Such kind of equalities can be generally represented in the equation form...
