On the Coarse Embeddability of l_p-Spaces Into l_2

Abstract

对l(_P-)空间与l_2之间粗嵌入关系作进一步的研究,证明了度量空间X可粗嵌入进l_2当且仅当存在某个20 such that X can be coarsely embedded into {l_p,2<p≤p_0} uniformly.This gave an equivalent condition for the coarse embeddability of metric spaces into l_2.国家自然科学基金(11101340;11201160); 福建省自然科学基金(2010J05012;2012J05006); 华侨大学高层次人才科研启动项目(11BS223
