On the total perimeter of disjoint convex bodies

Metric Geometry 2023-09-01 v1 Combinatorics

Abstract

In this note we introduce a pseudometric on convex planar curves based on distances between normal lines and show its basic properties. Then we use this pseudometric to give a short proof of the theorem by Pinchasi that the sum of perimeters of kk convex planar bodies with disjoint interiors contained in a convex body of perimeter pp and diameter dd is not greater than p+2(k1)dp+2(k-1)d.
