摘要:

引入区域的最大最小不等式性质, 研究最大最小不等式性质和一致域的关系, 得到了下述结果:
(1)区域的最大最小不等式性质具有拟共形不变性; (2)如果区域D是一致域, 则D具有最大最小不等式性质; (3)若D 和它的外部D*=R2\D 具有最大-最小不等式性质, 则DR2 中的一致域.

关键词: 一致域, 最大-最小不等式性质, 拟共形映射, 弱Cigar 域, 拟不变性, 双曲测地线

Abstract:

Introducing the max-min inequality property of domain,we investigate the relation between uniform domain and max-min inequality property, and obtain the following results: (1) if D is uniform domain, then D has max-min inequality property; (2) if D R2 and D*=R2\D have max-min inequality poperty, respectively, then D is uniform domain.

Key words: Uniform domain, Max-min inequality property, Weakly Cigar domain, Quasiconformal mappings, Quasi-invariance, Hyperbolic geodesic.
