The Dirichlet Problem for elliptic equations with singular drift terms

Analysis of PDEs 2026-01-05 v3

Abstract

We establish LpL^p solvability of the Dirichlet problem, for some finite pp, in a 1-sided chord-arc domain Ω\Omega (i.e., a uniform domain with Ahlfors-David regular boundary), for elliptic equations of the form Lu=div(Au)+Bu=:L0u+Bu=0, Lu=-\text{div}(A\nabla u) + {\bf B}\cdot \nabla u=:L_0 u+ {\bf B}\cdot \nabla u=0, given that the analogous result holds (typically with a different value of pp) for the homogeneous second order operator L0L_0. Essentially, we assume that B(X)dist(X,Ω)1|{\bf B}(X)|\lesssim \text{dist}(X,\partial \Omega)^{-1}, and that B(X)2dist(X,Ω)dX|{\bf B}(X)|^2\text{dist}(X,\partial \Omega) dX is a Carleson measure in Ω\Omega.

Comments

New version corrects an historical error in the introduction, pertaining to the cited paper [HL], regarding the doubling property of elliptic-harmonic measure for operators with a drift. A new section (Section 7) has been added, with a proof of doubling following the argument in [HL]
