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:
