DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Geolis/117/"
 >Symmetric probes and classification of toric fibres</a>\nby Joé Brendel 
 (School of Mathematical Sciences\, Tel Aviv University) as part of Geometr
 ia em Lisboa (IST)\n\n\nAbstract\nToric symplectic manifolds contain an in
 teresting and well-studied family of Lagrangian tori\, called toric fibres
 . In this talk\, we address the natural question of which toric fibres are
  equivalent under Hamiltonian diffeomorphisms of the ambient space. On one
  hand\, we use a symmetric version of McDuff's probes to construct such eq
 uivalences and on the other hand\, we give certain obstructions coming fro
 m Chekanov's classification of product tori in symplectic vector spaces co
 mbined with a lifting trick from toric geometry. We will discuss many four
 -dimensional examples in which a full classification can be achieved.\n
