## Homogenization and uniform stabilization for a nonlinear hyperbolic equation in domains with holes of small capacity.(English)Zbl 1053.35021

Summary: We study the homogenization and uniform decay of the nonlinear hyperbolic equation $\partial_{tt}u_\varepsilon-\Delta u_\varepsilon+ F(x,t,\partial_t u_\varepsilon,\nabla u_\varepsilon)=0\quad \text{in } \Omega_\varepsilon \times (0,+\infty)$ where $$\Omega_\varepsilon$$ is a domain containing holes with small capacity (i.e., the holes are smaller than a critical size). The homogenizations proofs are based on the abstract framework introduced by D. Cioranescu and F. Murat [Nonlinear partial differential equations and their applications, Coll. de France Semin., Vol. III. Res. Notes Math. 70, 154–178 (1982; Zbl 0498.35034)] for the study of homogenization of elliptic problems. Moreover, uniform decay rates are obtained by considering the perturbed energy method developed by A. Haraux and E. Zuazua [Arch. Ration. Mech. Anal. 100, No. 2, 191–206 (1988; Zbl 0654.35070)].
