Geometry and Physics XII, Hainan (China), 10-14/03/2014

Next year I’ll come to Sanya, Hainan, China to attend “GAP XII”, an international conference on geometry and physics.

The organizers said they would have money to cover local expenses for a number of participants, so if anyone is interested in visiting Sanya, please contact them (or contact me if you don’t know them)

List of books to be bought for the school on financial mathematics

We want to buy some books on financial mathematics and bring them to Vietnam for the thematic school in Doson (24/Oct-01/Nov/2011).After the school, these books will be donated to a library in Hanoi.

I need  a list of  best books to buy. If you have any suggestion, please let me know by writing a . . . → Read More: List of books to be bought for the school on financial mathematics

Poisson2010 Rio: symmetry leads to non-integrability !

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 !

Talk at “Colloque Chaperon”

My friend Marc has turned 60. Here’s a picture of a talk I gave in Paris in January in his honour.

Conference in memory of Paulette Libermann

Paulette Libermann: Héritage et descendence, Paris, 07-12/Dec/2009

Ici, l’affiche du colloque (version 25 avril 2009)

I’ll have to prepare a talk for this conference. Maybe rigidity of group actions on Poisson manifolds, or maybe  integrable systems with globally defined action functions ?

Here is a short biography of Paulette Libermann: http://www.agnesscott.edu/lriddle/WOMEN/libermann.htm
