DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Geolis/142/"
 >From Gromov-Witten invariants to dynamics</a>\nby Shira Tanny (Institute 
 for Advanced Study\, Princeton) as part of Geometria em Lisboa (IST)\n\n\n
 Abstract\nGiven a flow on a manifold\, how to perturb it in order to creat
 e a periodic orbit passing through a given region? This question was origi
 nally asked by Poincaré and was initially studied in the 60s. However\, v
 arious facets of it remain largely open. Recently\, several advances were 
 made in the context of Hamiltonian and contact flows. I will discuss a con
 nection between this problem and Gromov-Witten invariants\, which are ``co
 unts" of holomorphic curves. This is based on a joint work with Julian Cha
 idez.\n
