We show how pointwise lower bounds for positive weak solutions of degenerate parabolic equations can be derived from the intrinsic Harnack inequality they satisfy. This generalizes a result proved by Moser for linear parabolic equations with bounded and measurable coefficients.

Abstract
We show how pointwise lower bounds for positive weak solutions of degenerate parabolic equations can be derived from the intrinsic Harnack inequality they satisfy. This generalizes a result proved by Moser for linear parabolic equations with bounded and measurable coefficients.File in questo prodotto:
