Tel Aviv University 
 
Hello everyone,
 
The next colloquium talk will be held on Monday, 30/5/2011, Tel Aviv
University.
 
We will actually have two talks! The first talk, at the usual time and place
(12:15, Schreiber 006), will be given by
 
    Helmut Hofer (Institute for Advanced Study, Princeton)
 
and the title of his talk is
 
    Symplectic Dynamics.
 
His abstract is given below. Hofer's talk is part of the Blumenthal Lecture
series in Geometry. Tea and coffee at 12:00, same room.
 
(Details of the second talk, by Vladimir Rokhlin, will be sent in a separate Techmath message. M.C.)
 
Hope to see you there. For information about future colloquiua, see

You are all welcome to suggest colloquium speakers for the next academic
year.
 
Yours,
Bo'az

Abstract: The modern theories of dynamical systems and symplectic
geometry start with Poincare. Concerning Hamiltonian dynamics, Poincare had
a very integrated viewpoint combining geometric and dynamical ideas. Over
the time the two fields developed independently. Given the highly developed
states of both fields and the background of some promising results the time
seems ripe to bring them together around the core of Hamiltonian mechanics,
resulting (may be) in a field which one could call "Symplectic Dynamics". It
should have a body of theory and techniques which combine in a nontrivial
way dynamical and symplectic ideas, with the aim to tackle problems which
are neither accessible by dynamical ideas nor by purely symplectic ideas.
The talk will give some ideas what this field would be about.
