A Fixed Point Theorem for Monotone Maps and Its Applications to Nonlinear Matrix Equations
By using the fixed point theorem for monotone maps in a normal cone, we prove a uniqueness theorem for the positive definite solution of the matrix equation X=Q+A⁎f(X)A, where f is a monotone map on the set of positive definite matrices. Then we apply the uniqueness theorem to a special equation X=k...
