There is no class on Feb. 20, during the reading week.

Syllabus:
  1. Billiards, symplectic structure on lines, Crofton's formula
  2. Integrability of the geodesic flow on an ellipsoid
  3. Hamiltonian systems, first integrals, the Arnold-Liouville theorem, tori
  4. Lie algebras, the Lie-Poisson bracket; example: a rigid body
  5. Bihamiltonian systems, the Lenard-Magri scheme, the Lax form; example: the Toda lattice

  11. Topics and generalizations (time permitted):
Lecture notes: References: Prerequisite:

The undergraduate courses of differential geometry and ODE are a necessity, while some familiarity with the main notions of classical mechanics or symplectic geometry will be useful, but not required.
