The spectral diameter of a symplectic ellipsoid

Symplectic Geometry 2024-08-15 v1

Abstract

The spectral diameter of a symplectic ball is shown to be equal to its capacity; this result upgrades the known bound by a factor of two and yields a simple formula for the spectral diameter of a symplectic ellipsoid. We also study the relationship between the spectral diameter and packings by two balls.
