Simplices in Newton-Okounkov bodies and the Gromov width of coadjoint orbits

Abstract

We give a uniform proof for the conjectured Gromov width of coadjoint orbits of all compact connected simple Lie groups, by analyzing simplices in Newton-Okounkov bodies.

A mistake (missing assumption that λis on a rational line) is now corrected. We have also implemented valuable comments of referees, improving the exposition
