## Texts

The official text is The structure of dynamical systems. A symplectic view of physics by J.-M. Souriau

Lecture notes of an old version of the course are available here pdf file

You may also wish to look at a set of notes by Ana Cannas
PostScript file
A new version of these notes should be available soon.

Recommended texts:

- Symplectic geometry and analytical mechanics
by P. Liebermann and C.-M. Marle
- Introduction to
Mechanics and Symmetry by J. E. Marsden and T. S. Ratiu
- Symplectic Techniques in Physics by V. Guillemin and
S. Sternberg

## Grades

The course grade will be based on homework.
Homework will be assigned weekly. One problem per homework will be
graded.
