Energy decay estimates for a Kirchhoff model with viscosity

Il Hyo Jung and Jongsool Choi

Pusan National University, Korea Science Academy

Abstract

In this paper we study the uniform decay estimates of the energy for the nonlinear wave equation of Kirchhoff type \begin{equation*} y''(t) - M(|\str y(t)|^2)\tr y(t) + \delta y'(t) = f(t) \end{equation*} with the damping constant $\delta >0$ in a bounded domain $\Omega \subset {\Bbb R}^n$.

Keywords: stabilization, quasilinear hyperbolic equation, Kirchhoff equation, asymptotic behavior, energy decay
