Abstract

In this note we establish two-sided pointwise estimates near the pole of the Green function for \(X\)-elliptic 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.
