Resumen inglés	When does a metric space admit a bilipschitz embedding into some finite-dimensional Euclidean space? There does not seem to be a simple answer to this question. Results of Assouad [A1], [A2], [A3] do provide a simple answer if one permits some small ("snowflake") deformations of the metric, but unfortunately these deformations immediately disrupt some basic aspects of geometry and analysis, like rectifiability, differentiability, and curves of finite length. Here we discuss a (somewhat technical) criterion which permits more modest deformations, based on small powers of an A1 weight. For many purposes this type of deformation is quite innocuous as in standard results in harmonic analysis about Ap weights [J], [Ga], [St2]. In particular, it cooperates well with uniform rectifiability [DS2], [DS4].
