Geometry of Gelfand-Cetlin integrable system (Conservative dynamics and symplectic geometry 2009):
Dynamics on Poisson manifolds (Poisson 2010):
(now that I listened to my own talk at IMPA, I found that my English was really horrible !)
For all video lectures recorded by IMPA:
Yesterday (July 26) I gave a talk at “Poisson 2010” at IMPA. The talk was about the entropy of Poisson manifolds, normal forms (of Hamiltonian systems on Poisson manifolds), resonances, and (non)integrability, and was dedicated to the memory of JJ Duistermaat (who is well-known for Fourier operators and symplecitc geometry, but also did a . . . → Read More: Poisson2010 Rio: symmetry leads to non-integrability !
I’m very sad to learn that my friend and colleague Naoufel Ben Abdallah suddenly passed away yesterday (05 July) in a car accident. It’s a great loss for our mathematical community in Toulouse. And it reminds me how dangerous it is to drive when you’re tired or sleepy.
Naoufel was a brilliant applied mathematician . . . → Read More: R.I.P. Naoufel
