Resumo

In this work, we analyze the asymptotic behavior of a class of quasilinear elliptic equations defined in oscillating (N+ 1)-dimensional thin domains (i.e., a family of bounded open sets from RN+ 1, with corrugated bounder, which degenerates to an open bounded set in R-N). We also allow monotone nonlinear boundary conditions on the rough border whose magnitude depends on the squeezing of the domain. According to the intensity of the roughness and a reaction coefficient term on the nonlinear boundary condition, we obtain different regimes establishing effective homogenized limits in N-dimensional open bounded sets. In order to do that, we combine monotone operator analysis techniques and the unfolding method used to deal with asymptotic analysis and homogenization problems. (AU)
