• Nonlinear wave equations
• initial boundary value problem
• exponential decay

This article concerns the decay of solutions of the semi-linear wave equation u(tt) + delta u(t) - phi(x)Delta u = lambda u vertical bar u vertical bar(beta-1) x is an element of R-N t >= 0 Introducing an appropriate Lyaponuv function, we find exponential decay for certain initial data
