Chen M. and et al. have solved the open problem related to rank equalities for the sum of finitely many idempotent matrices by using the Gussian elimination method (Chen M. and et al. “On the open problem related to rank equalities for the sum of finitely many idempotent matrices and its applications”, The Scientific World Journal, 2014). In this work, it is obtained a similar rank equality for the sum of finitely many involutive matices and derived some results from this equality.
