DESCRIPTION:A Poincaré surface can be a powerful tool for analysing a dyn
 amical system in low dimensions.  An interesting  connection to pseudo-hol
 omorphic curves was discovered in the late 90's by Hofer-Wysocki-Zehnder. 
   But it remains difficult to construct the pseudo-holomorphic curves one 
 would like to have.   A natural way to overcome this problem leads to a ne
 w version of Floer's Morse theory of the action functional in low dimensio
 ns\, using so called unlinked collections of periodic orbits - a concept t
 aken from LeCalvez' work on surface homeomorphisms.   I will describe this
  "unlinked" Floer homology and what it gives us.  \n
