Uniform Decay for a Viscoelastic Wave Equation with Density and Time-Varying Delay in R^n

Salah Zitouni, khaled zennir, Lamine Bouzettouta


A linear viscoelastic wave equation with density and a time-varying delay term
in the internal feedback is considered. Under suitable assumptions on the relaxation
function, we establish a decay result of solution for by using energy perturbation
method in the space Rn (n > 2). We extend a recent result in Feng [10].
