On Uniform Domains

DeparUnent of Applied Mathematics, Beijing Institute of Technology, Beijing 100081

Abstract

A characteristic parameter α _Dof a domain D in R ⁿis introduced. D is unifonm if and only if α _D<∞. And α _D=1 if D is a ball or a half space. It is proved that the decomposability and the uniformity of a domain in R ⁿare still equivalent. Some problems on uniform domains and decomposition domains are discussed.
