General Energy Decay Rates for a Weakly Damped Wave Equation

Price: $20.00

Abstract

In this paper we consider a wave equation with a weak frictional damping. We establish an explicit and general decay rate result, using some properties of convex functions. Our result is obtained without imposing any restrictive growth assumption on the frictional damping term..
