Local fixed point results for centroid body operators

Metric Geometry 2024-08-27 v2

Abstract

We prove that, in a neighborhood of the Euclidean ball, there are no other fixed points of the pp-centroid body operator, using spherical harmonic techniques. We also show that the Euclidean ball is locally the only body whose centroid body is a dilate of its polar intersection body.
