Generalized inverses of Hankel and Toeplitz mosaic matrices
Hankel and Toeplitz mosaic matrices are block matrices with Hankel and Toeplitz blocks respectively. The author considers several kinds of generalized inverses of Hankel and Toeplitz mosaic matrices (reflexive generalized inverse, inner generalized inverse, Moore-Penrose inverse and group inverse) and defines the structure of the Bezoutian. The aim of this paper is to generalize known theorems on generalized inverses, with the structure of Bezoutian, of Hankel and Toeplitz matrices, to Hankel and Toeplitz mosaic matrices.
