Abstract: In this paper, combining generalized Schur complements of matrices with Kronecker products of matrices and compound matrices, we study some Löwner partial orders for Kronecker products and compound matrices of products of Schur complements of matrices, and obtain an inequality for singular values of Kronecker products of matrices, thus improve recent results.

Key words: generalized Schur complement of matrix, Kronecker product, compound matrix;Löwner partial order;singular value
