Asymptotic behaviour of Green functions of divergence form operators   with periodic coefficients
  This article is concerned with the asymptotic behaviour, at infinity and at the origin, of Green functions of operators of the form $Lu = -\text{div} (A \nabla u),$ where $A$ is a periodic, coercive and bounded matrix.
