Barycenters of points that are constrained to a polytope skeleton

Metric Geometry 2015-11-16 v2 Combinatorics

Abstract

We give a short and simple proof of a recent result of Dobbins that any point in an ndnd-polytope is the barycenter of nn points in the dd-skeleton. This new proof builds on the constraint method that we recently introduced to prove Tverberg-type results.
