Extremal ranks of a quaternion matrix expression subject to consistent systems of quaternion matrix equations with applications

Applied Mathematics and Computation, 2006
The authors consider the maximal and minimal ranks of the matrix function \(f(X_1,X_2)=A-A_3X_1B_3-A_4X_2B_4\) where the quaternion matrices \(X_1\), \(X_2\) are subject to the consistent systems of quaternion matrix equations \(A_1X_1=C_1\), \(X_1B_1=C_2~(*)\) and \(A_2X_2=C_3\), \(X_2B_2=C_4~(**)\).
