Abstract: We study a notion of topological entropy for switched systems, formulated in terms of the minimal number of initial states needed to approximate all initial states within a finite precision.

Abstract: It is well known that some matrices (such as Dickinson-Steiglitz's matrix) can commute with the discrete Fourier transform (DFT) and that one can use them to derive the complete and ...

Journal of Operator Theory, Vol. 55, No. 2 (Spring 2006), pp. 295-310 (16 pages) We consider a condition for non-degenerate commuting squares of matrix algebras (finite dimensional von Neumann ...

ABSTRACT: The current paper is mainly devoted for solving centrosymmetric linear systems of equations. Formulae for the determinants of tridiagonal centrosymmetric matrices are obtained explicitly.
