Abstract

We establish necessary and sufficient conditions for the existence of and the expressions for the general real and complex Hermitian solutions to the classical system of quaternion matrix equations . Moreover, formulas of the maximal and minimal ranks of four real matrices , and in solution to the system mentioned above are derived. As applications, we give necessary and sufficient conditions for the quaternion matrix equations , and to have real and complex Hermitian solutions.
