Optimal boundary regularity and a Hopf-type lemma for Dirichlet problems involving the logarithmic Laplacian

Analysis of PDEs 2024-07-08 v2

Abstract

We study the optimal boundary regularity of solutions to Dirichlet problems involving the logarithmic Laplacian. Our proofs are based on the construction of suitable barriers via the Kelvin transform and direct computations. As applications of our results, we show a Hopf-type Lemma for nonnegative weak solutions and the uniqueness of solutions to some nonlinear problems.
