Affine functions on Alexandrov spaces

Metric Geometry 2017-11-02 v2 Differential Geometry

Abstract

We show that every finite-dimensional Alexandrov space X with curvature bounded from below embeds canonically into a product of an Alexandrov space with the same curvature bound and a Euclidean space such that each affine function on X comes from an affine function on the Euclidean space.
