Abstract

In a bounded domain, we consider utt- Δu+∫t0g(t-τ)Δudτ=|u|γu, where γ>0, and g is a nonnegative and decaying function. We prove a local existence theorem and show, for certain initial data and suitable conditions on g and γ, that this solution is global with energy which decays exponentially or polynomially depending on the rate of the decay of the relaxation function g.
