We introduce a new condition allowing to get a weak Harnack inequality for non-negative solutions to linear second order degenerate elliptic equations of $X$-elliptic type. Roughly speaking, our condition requires that the Euclidean balls of small radius are representable by means of $X$-controllable almost exponential maps.

Abstract
We introduce a new condition allowing to get a weak Harnack inequality for non-negative solutions to linear second order degenerate elliptic equations of $X$-elliptic type. Roughly speaking, our condition requires that the Euclidean balls of small radius are representable by means of $X$-controllable almost exponential maps.File in questo prodotto:
