Proof of the simplicity conjecture
Dan Cristofaro-Gardiner, Vincent Humilière, Sobhan Seyfaddini
In the 1970s, Fathi, having proven that the group of compactly supported volume-preserving homeomorphisms of the -ball is simple for , asked if the same statement holds…
The action spectrum characterizes closed contact 3-manifolds all of whose Reeb orbits are closed
Daniel Cristofaro-Gardiner, Marco Mazzucchelli
A classical theorem due to Wadsley implies that, on a connected contact manifold all of whose Reeb orbits are closed, there is a common period for the Reeb orbits. In this paper we…
Sub-leading asymptotics of ECH capacities
Daniel Cristofaro-Gardiner, Nikhil Savale
In previous work, the first author and collaborators showed that the leading asymptotics of the embedded contact homology (ECH) spectrum recovers the contact volume. Our main theor…
The absolute gradings on embedded contact homology and Seiberg-Witten Floer cohomology
Daniel Cristofaro-Gardiner
Let Y be a closed connected contact 3-manifold. In the series of papers "Embedded contact homology and Seiberg-Witten Floer cohomology I-V", Taubes defines an isomorphism between t…
