8. Global existence and stability of a nonlinear wave equation with variable-exponent nonlinearities.

Author

Ghegal, Samah, Hamchi, Ilhem, and Messaoudi, Salim A.

Subjects
*NONLINEAR wave equations, *GLOBAL analysis (Mathematics), *WAVE equation, *INTEGRAL inequalities
Abstract

In this paper, we consider a nonlinear wave equation with damping and source terms of variable-exponent types. First, we use the stable-set method to prove a global result. Then, by applying an integral inequality due to Komornik, we obtain the stability result. [ABSTRACT FROM AUTHOR]

10. Exponential Decay Rate of the Perturbed Energy of the Wave Equation with Zero Order Term

Author

Hamchi Ilhem

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.

14. Blow up of two coupled wave equations with internal/boundary damping and source terms.

Author

Imane, Boulmerka and Ilhem, Hamchi

Subjects
INTERNAL waves, WAVE equation, BLOWING up (Algebraic geometry)
Abstract

In this paper. we consider a system of two coupled wave equations with internal/boundary damping and source terms. The aim of this work is to prove two blow up results in finite time: the first one is concerned with solution with negative initial energy. The second one is concerned with solution with positive initial energy. [ABSTRACT FROM AUTHOR]
