In this paper we study the asymptotic behavior of the viscoelastic system with non dissipative kernels. We show that the uniform decay of the energy depends on the decay of the kernel, the positivity of the kernel in t = 0 and some smallness condition. That is, if the kernel g ∈ C^2(R^+) with g(0) > 0, decays exponentially to zero then the solution decays exponentially to zero. On the other hand, if the kernel decays polynomially as t^{−p} then the corresponding solutions also decays polynomially to zero with the same rate of decay

Abstract
In this paper we study the asymptotic behavior of the viscoelastic system with non dissipative kernels. We show that the uniform decay of the energy depends on the decay of the kernel, the positivity of the kernel in t = 0 and some smallness condition. That is, if the kernel g ∈ C^2(R^+) with g(0) > 0, decays exponentially to zero then the solution decays exponentially to zero. On the other hand, if the kernel decays polynomially as t^{−p} then the corresponding solutions also decays polynomially to zero with the same rate of decayFile in questo prodotto:
