Block Toeplitz Matrices: Multiplicative Properties

Functional Analysis 2023-07-31 v7

Abstract

Given A,B,CA,B,C and DD block Toeplitz matrices, we will prove some of the basic results concerning the product ABCDAB-CD. In addition, with respect to change of basis, the characterization of normal block Toeplitz matrices with entries in the algebra of diagonal matrices is also obtained.
