On the Hopf boundary lemma for quasilinear problems involving singular nonlinearities and applications

摘要

In this paper we consider positive solutions to quasilinear elliptic problem with singular nonlinearities. We provide a Hopf type boundary lemma via a suitable scaling argument that allows to deal with the lack of regularity of the solutions up to the boundary. (C) 2019 Elsevier Inc. All rights reserved.
