When introduced at the wrong time or place, good logic may be the worst enemy of good teaching.
by Polya George (1887, 1985)

Poisson Book

The first chapters of this book, written with Jean-Paul Dufour and published by Birkhauser in 2005, may serve as an introduction to Poisson geometry for interested people.

As regards normal forms, there are a number of interesting results which appeared in the literature after the publication of the book. In particular:

* The results by Cranic, Fernandes, Marcut, … (In particular, Crainic has a nice geometric proof of my local linearization theorem for proper Lie groupoids)

* The results by Stolovitch, Lorhmann, … (analytic/Gevrey local normal forms)

Comments welcome (especially about new developments)
