The Martin Boundary in Non-lipschitz Domains
نویسنده
چکیده
The Martin boundary with respect to the Laplacian and with respect to uniformly elliptic operators in divergence form can be identified with the Euclidean boundary in Cγ domains, where γ(x) = bx log log(1/x)/ log log log(1/x), b small. A counterexample shows that this result is very nearly sharp.

Boundary Harnack principle for Brownian motions with measure-valued drifts in bounded Lipschitz domains
Let μ = (μ1, . . . , μd) be such that each μi is a signed measure on Rd belonging to the Kato class Kd,1. A Brownian motion in Rd with drift μ is a diffusion process in Rd whose generator can be informally written as 1 2 + μ · ∇. When each μi is given by Ui (x)dx for some function Ui , a Brownian motion with drift μ is a diffusion in Rd with generator 1 2 +U ·∇. In Kim and Song (Ill J Math 50(3...
متن کاملUniqueness Theorems for Inverse Obstacle Scattering Problems in Lipschitz Domains
For the Neumann and Robin boundary conditions the uniqueness theorems for inverse obstacle scattering problems are proved in Lipschitz domains. The role of non-smoothness of the boundary is analyzed.

Lipschitz domains. Our presentations here will almost exclusively be for bounded Lipschitz domains. Roughly speaking, a domain (a connected open set) Ω ⊂ R is called a Lipschitz domain if its boundary ∂Ω can be locally represented by Lipschitz continuous function; namely for any x ∈ ∂Ω, there exists a neighborhood of x, G ⊂ R, such that G ∩ ∂Ω is the graph of a Lipschitz continuous function und...
متن کاملBoundary-value problems for higher-order el- liptic equations in non-smooth domains
This paper presents a survey of recent results, methods, and open problems in the theory of higher order elliptic boundary value problems on Lipschitz and more general non-smooth domains. The main topics include the maximum principle and pointwise estimates on solutions in arbitrary domains, analogues of the Wiener test governing continuity of solutions and their derivatives at a boundary point...
متن کاملA Remark on the Regularity of Solutions of Maxwell's Equations on Lipschitz Domains
Let ~ u be a vector eld on a bounded Lipschitz domain in R 3 , and let ~ u together with its divergence and curl be square integrable. If either the normal or the tangential component of ~ u is square inte-grable over the boundary, then ~ u belongs to the Sobolev space H 1=2 on the domain. This result gives a simple explanation for known results on the compact embedding of the space of solution...
