Linear Lipschitz and $C^1$ extension operators through random projection

Functional Analysis 2018-01-24 v1 Metric Geometry

Abstract

We construct a regular random projection of a metric space onto a closed doubling subset and use it to linearly extend Lipschitz and C1C^1 functions. This way we prove more directly a result by Lee and Naor and we generalize the C1C^1 extension theorem by Whitney to Banach spaces.
