The ghost stairs stabilize to sharp symplectic embedding obstructions
Dan Cristofaro-Gardiner, Richard Hind, Dusa McDuff
In determining when a four-dimensional ellipsoid can be symplectically embedded into a ball, McDuff and Schlenk found an infinite sequence of "ghost" obstructions that generate an…

Torsion contact forms in three dimensions have two or infinitely many Reeb orbits
Dan Cristofaro-Gardiner, Michael Hutchings, Dan Pomerleano
We prove that every nondegenerate contact form on a closed connected three-manifold, such that the associated contact structure has torsion first Chern class, has either two or inf…
