Abstract in Portuguese
Nesse trabalho, usamos métodos da teoria de homogeneização para analisar o compor- tamento assintótico das soluções da equação do p-Laplaciano com condição de contorno de Neumann posto numa família de domínios finos do tipo. De maneira geral, trabalhamos com funções G:(0,1)\ x R - R uniformemente limitadas, suaves e L-periódicas na segunda variável. Note que o efeito de domínio fino é estabelecido passando ao limite no parâmetro \varepsilon>0 com \varepsilon\to 0. Além disso, introduzimos um parâmetro \alpha>0 com o objetivo de representar rugosidades via comportamento oscilat\'orio na fronteira superior de R^\varepsilon. Em nossos resultados mostramos que no limite, uma equação unidimensional é obtida, preservando a quasilinearidade do problema original e capturando tanto o efeito da compressão como das oscilações.

Abstract in English
In this work we apply homogenization theory methods in order to analyze the asymptotic behavior of the solutions of a p-Laplacian equation with Neumann boundary condition set in bounded thin domains of the type. Generally, we with functions G:(0,1) x R - R uniformly bounded, smooth and L-periodic in the second variable. The thin domain situation is established passing to the limit in the positive parameter \varepsilon with \varepsilon \to 0. In our results we obtain a one dimensional equation that preserves the quasilinearity from the original problem and capturing the effects of compression and oscillations.
