Abstract
In this note we establish twosided pointwise estimates near the pole of the Green function for Xelliptic operators in divergence form enjoying the doubling condition and the Poincaré inequality As a step towards this result we also prove a nonhomogeneous Harnack inequality some representation formulas and a result on approximation by regular domains
