On the Open Problem Related to Rank Equalities for the Sum of Finitely Many Idempotent Matrices and Its Applications
Tian and Styan have shown many rank equalities for the sum of two and three idempotent matrices and pointed out that rank equalities for the sum P (1) + ⋯+P (k) with P (1),…, P (k) be idempotent (k > 3) are still open. In this paper, by using block Gaussian elimination, we obtained rank equalitie...
