Abstract
In this paper we deal with the limit behaviour of the solutions uh of quasi-linear equations -div f on perforated domains with homogeneous Neumann boundary conditions on the holes. Under suitable assumptions on ah and ωh we prove that certain extensions of uh converge weakly in H1,p(ω) to the solution u of a quasi-linear equation of the form -div(a(x,Du)) = f, where the function a is independent of f and has the same qualitative properties of ah
