On convergence of infinite matrix products with alternating factors from two sets of matrices
, 2018 We consider the problem of convergence to zero of matrix products $A_{n}B_{n}\cdots A_{1}B_{1}$ with factors from two sets of matrices, $A_{i}\in\mathscr{A}$ and $B_{i}\in\mathscr{B}$, due to a suitable choice of matrices $\{B_{i}\}$.

The analysis of exact controllability of neutral type systems by the moment problem approach [PDF]
, 2007 Presented also at the 47th IEEE CDCInternational audienceThe problem of exact null-controllability is considered for a wide class of linear neutral-type systems with distributed delay.

Null controllability of a nonlinear heat equation
Abstract and Applied Analysis, Volume 7, Issue 7, Page 375-383, 2002., 2002 We study the internal exact null controllability of a nonlinear heat equation with homogeneous Dirichlet boundary condition. The method used combines the Kakutani fixed‐point theorem and the Carleman estimates for the backward adjoint linearized system. The result extends to the case of boundary control.

A Semigroup associated to a linear control system on a Lie group
, 2016 Let us consider a linear control system \Sigma on a connected Lie group G. It is known that the accessibility set A from the identity e is in general not a semigroup. In this article we associate a new algebraic object S to \Sigma which turns out to be a

Null controllability of a thermoelastic plate
Abstract and Applied Analysis, Volume 7, Issue 11, Page 585-599, 2002., 2002 Thermoelastic plate model with a control term in the thermal equation is considered. The main result in this paper is that with thermal control, locally distributed within the interior and square integrable in time and space, any finite energy solution can be driven to zero at the control time T.

Approximate controllability of neutral functional differential system with unbounded delay
International Journal of Mathematics and Mathematical Sciences, Volume 26, Issue 12, Page 737-744, 2001., 2001 We consider a class of control systems governed by the neutral functional differential equation with unbounded delay and study the approximate controllability of the system. An example is given to illustrate the result.

Controllability of semilinear stochastic evolution equations in Hilbert space
International Journal of Stochastic Analysis, Volume 14, Issue 4, Page 329-339, 2001., 2001 Controllability of semilinear stochastic evolution equations is studied by using stochastic versions of the well‐known fixed point theorem and semigroup theory. An application to a stochastic partial differential equation is given.

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020 This manuscript involves a class of first-order controllability results for nonlocal non-autonomous neutral differential systems with non-instantaneous impulses in the space n. Sufficient conditions guaranteeing the controllability of mild solutions are
