• TITLE: Exponential Decay Rate of the Perturbed Energy of the Wave Equation with Zero Order Term

  AUTHORS: Hamchi Ilhem

  KEYWORDS: Perturbed Energy, Compactness Uniqueness Argument

  JOURNAL NAME: Advances in Pure Mathematics, Vol.1 No.5, September 21, 2011

  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.
