Analysis and geometry near the unit ball: proofs, counterexamples, and open questions
-
M. Angeles Alfonseca
Abstract
We present several theorems, counterexamples, and open questions related to convex bodies close to the unit ball. The techniques include spherical harmonic decomposition and some elements of perturbation theory. We hope that this short survey will attract the attention of both young and mature researchers who will be able to surpass our results and resolve some questions we left unanswered.
