Author: Hamchi Ilhem
Subjects: Boundary stabilization, Schrodinger equation, multiplier method., Mathematics, QA1-939
Abstract: We use the multiplier method and the approach in [1] to study the problem of exponential stabilization of a coupled system of two Schrodinger equations.

Subjects: Zero order, Compact space, Mathematical analysis, General Medicine, Uniqueness, Exponential decay, Wave equation, Energy (signal processing), Mathematics, Term (time)
Abstract: In this paper, we consider the wave equation with zero order term. We use the compactness uniqueness argument and some result of I. Lasiecka and D. Tataru in [4] to prove, directly, the exponential decay rate of the perturbed energy.

Abstract: In this paper, we consider a second-order hyperbolic equations with variable coefficients and linear lower-order term. We use a new main multiplier and a suitable nonlinear version of a compactness uniqueness argument (Acta. Math. Sin. – Engl. Ser. 20(6) (2004), 1057–1072) to obtain the exponential stabilization of this system where no condition of smallness is needed. [ABSTRACT FROM AUTHOR]
