Reversing A Doodle


The radius r neighborhood of a set X, denoted Nr(X), is the collection of points within a distance r of X. We discuss some of the properties preserved by the radius r neighborhood in Rn. In particular, we find a collection of sets which have a unique pre-image when mapped under Nr. This problem has interesting ties to convex geometry.
