Title: Lower bounds for the number of fixed points of periodic flows
Speaker: Leonor Godinho (Instituto Superior Técnico)
Abstract: Finding the minimal number of fixed points of a periodic flow on a compact manifold is, in general, an open problem. We will see how one can obtain lower bounds for the number of fixed points of a circle action on an almost complex manifold, by retrieving information from a special Chern number.
