Abstract In the present paper, we generalize the theory of quantitative homogenization for second-order elliptic systems with rapidly oscillating coefficients in A P W 2 ( R d ) , which is the space of almost-periodic functions in the sense of H. Weyl. We obtain the large scale uniform boundary Lipschitz estimate, for both Dirichlet and Neumann problems in C 1 , α domains. We also obtain large scale uniform boundary Holder estimates in C 1 , α domains and L 2 Rellich estimates in Lipschitz domains.
