Applications of ECH to dynamics and topology in dimension 3
Vendredi, 22 Mars, 2024 - 10:30
Résumé : 

Embedded contact homology (ECH) is a Floer type invariant of 3-manifolds 
built out of the auxiliary data of a contact structure and a Reeb vector 
field. We will survey interactions between the various structures 
arising from ECH theory and the dynamics of Reeb vector fields.
In particular, joint works with Pierre Dehornoy, Umberto Hryniewicz and 
Ana Rechtman on the one hand, and Paolo Ghiggini and Ko Honda on the 
other will be discussed.
