Coarse and uniform embeddings

Functional Analysis 2016-12-23 v2

Abstract

In these notes, we study the relation between uniform and coarse embeddings between Banach spaces. In order to understand this relation better, we also look at the problem of when a coarse embedding can be assumed to be topological. Among other results, we show that if a Banach space XX uniformly embeds into a minimal Banach space YY, then XX simultaneously coarsely and uniformly embeds into YY, and if a Banach space XX coarsely embeds into a minimal Banach space YY, then XX simultaneously coarsely and homeomorphically embeds into YY by a map with uniformly continuous inverse.
