Homogenization and uniform stabilization for a nonlinear hyperbolic equation in domains with holes of small capacity

Abstract

In this article we study the homogenization and uniform decay of the nonlinear hyperbolic equation ∂ttuɛ - Δuɛ + F(x, t, ∂tuɛ, ∇uɛ) = 0 in Ωɛ x (0, +∞) where Ωɛ is a domain containing holes with small capacity (i.e. the holes are smaller than a critical size). The homogenization's proofs are based on the abstract framework introduced by Cioranescu and Murat [8] for the study of homogenization of elliptic problems. Moreover, uniform decay rates are obtained by considering the perturbed energy method developed by Haraux and Zuazua [10].
