On Schur-Cohn Stability of a Product of Operators in a Hilbert Space
Journal Title: Discussiones Mathematicae Differential Inclusions Control and Optimization - Year 2017, Vol 37, Issue 1
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.

Random integral guiding functions with application to random differential complementarity systems
By applying the random topological degree we develop the methods of random smooth and nonsmooth integral guiding functions and use them for the study of random differential inclusions in finite dimensional spaces. Some e...
Stochastic nonlinear Schrödinger equation and its laser induced optimal feedback control
In this paper we consider a class of nonlinear stochastic Schrödinger equations and their optimal control through laser induced electro-magnetic field. These equations arise in the field of optics. We prove existence and...
Controllability for some integrodifferential evolution equations in Banach spaces
In this work, we study the controllability for a class of nonlinear integrodifferential equations in Banach spaces. Using resolvent operator properties and Schaefer's fixed point Theorem, we give sufficient conditions fo...
Fractional Differential Inclusions of Hilfer and Hadamard Types in Banach Spaces
We deal in this paper with some existence results in Banach spaces for some Hilfer and Hadamard differential inclusions of fractional order. The Mönch's fixed point theorem and the concept of measure of noncompactness ar...
Unbounded perturbation for a class of variational inequalities
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...
