Abstract
This paper establishes a quantitative version of the Hopf–Oleinik lemma (HOL)for a quasilinear non-uniformly elliptic operator of the formL∞u:= 2∆∞u+ ∆u. One key point inthe proof is the passage from non-uniformly elliptic operators to locally uniformly ones via a new,uniform, and, rescaled version of the gradient estimate obtained by Evans and Smart for solutionsto a family of non-uniformly quasilinear elliptic operators.File in questo prodotto:
