摘要
We study the asymptotic behaviour of the following nonlinear problem: GRAPHICS in a domain Omega(h) of R-n whose boundary partial derivative Omega(h) contains an oscillating part with respect to h when h tends to infinity. The oscillating boundary is defined by a set of cylinders with axis 0x(n) that; are h(-1)-periodically distributed. We prove that the limit problem in the domain corresponding to the oscillating boundary identifies with a diffusion operator with respect to x(n) coupled with an algebraic problem for the limit fluxes.
