Solutions of a constrained Hermitian matrix-valued function optimization problem with applications. (English) Zbl 1357.65079

The paper considers a group of problems on ranks/inertias, equalities/inequalities, minimization/maximization in the Löwner partial ordering of a Hermitian matrix-valued function subject to a linear matrix equation by using algebraic operations of the given matrices in the function and restriction. The author presents results in solving problems on Hermitian matrix-valued functions subject to linear matrix equation restrictions where the Lagrangian method is not available.
