Abstract

This paper is concerned with the periodic homogenization of second-order elliptic systems in divergence form with oscillating Dirichlet data or Neumann data of first order. We prove that the homogenized boundary data belongs to W1,p for any 1 < p < ∞. In particular, this implies that the boundary layer tails are Hölder continuous of order α for any α ∈ (0, 1).
