Résumé
Abstract

Nous étudions les solutions d'équations quasilinéaires elliptiques à coefficients fortement contrastés. La formulation variationnelle associée conduit à travailler dans des espaces de Lebesgue à exposant variable $L^{p_{ε} (\cdot)}$ dans des domaines à la microstructure complexe caractérisée par un petit paramètre ε. Nous obtenons rigoureusement le problème homogénéisé correspondant. Il est déterminé par les caractéristiques variationnelles locales de la microstructure.

We study the solutions to quasilinear elliptic equations with high contrast coefficients. The energy formulation leads to work with variable exponent Lebesgue spaces $L^{p_{ε} (\cdot)}$ in domains with a complex microstructure scaled by a small parameter ε. We derive rigorously the corresponding homogenized problem. It is completely described in terms of local energy characteristics of the original domain.
