Yuhan Sun (Imperial). Rigid fibers in symplectic and contact manifolds
Abstract: Given a Hamiltonian integrable system on a closed symplectic manifold, Entov-Polterovich proved it has at least one rigid fiber. We will first survey several ideas of the proof and recent enhancements. Then we will present a rigid fiber theorem for contact manifolds. Based on joint works with Mak, Uljarevic and Varolgunes.
