In this article we prove a theorem on the size of the image of sections of a convex function under its normal mapping when the sections satisfy a geometric property. We apply this result to get new geometric characterizations for Monge-Ampère doubling measures. © 2002 Elsevier Science (USA). All rights reserved.
