Jean Gutt will talk in the geometry seminar on 10th November, at 2pm in the Salle des Profs (9th floor building NO). Jean’s title is “Ekeland-Hofer capacities from positive S^1 equivariant symplectic homology” and his abstract is below.
Associated to a star-shaped domain in R^2n are two increasing sequences of capacities: the Ekeland-Hofer capacities and the so-called Gutt-Hutchings capacities. I shall recall both constructions and then present the main theorem that they are the same. This is joint work with Vinicius Ramos.
