On Schur-Cohn Stability of a Product of Operators in a Hilbert Space

Abstract

A linear operator is said to be a Schur-Cohn stable one if its spectral radius is less than one. We consider the following problem: let A and B be bounded linear operators in a Hilbert space, and A be Schur-Cohn stable. What conditions provide the Schur-Cohn stability of AB? Our stability conditions for AB are formulated in terms of the commutator AB-BA.

In this paper, we prove the existence of solutions of a class of variational inequalities known as the so-called second order "sweeping process" with perturbations. We deal with the nonconvex case using some definition o...

We consider ordinary differential inclusions and we state and discuss some averaging results for these inclusions. Our results are proved under weaker conditions than the results in the literature.
