I will start with classical examples of mechanical systems and reformulate them as a Hamiltonian systems of differential equations. Then I will discuss some of the features of the solutions, symmetries, integrals etc. of Hamiltonian equations.
Then I will go global and introduce symplectic manifolds. Hamiltonian flows live naturally on such manifolds. I will end with a discussion of the MMW reduction theorem for Hamiltonian systems with symmetries.
Everyone should know the basics of differential manifolds. The first few chapters of "Differential Topology" by M. W. Hirsch should be good enough.

Introduction to Symplectic and Poisson Geometry
In this 10 hour mini-course, we will attempt to cover some basic materials in symplectic and Poisson geometry and point out some research problems in these fields. The course outline is as follows:
Day 1: Definition of Poisson manifolds, examples, and basic properties;
Day 2: Symplectic manifolds and examples;
Day 3: Moment maps and symplectic reduction;
Day 4: Poisson Lie groups and Lie bialgebras;
Day 5: Poisson homogeneous spaces
Prerequisites: First year course on differential manifolds; One semester of Lie theory (for the second half of the course).

Integrable Systems
In this mini-course, I plan to review basic techniques and constructions of the theory of integrable systems. We shall discuss Lax formalism, several versions of the inverse problem method, Lie algebraic approach to constructing exactly solvable Hamiltonian equations and an interplay between complete integrability and exact solvability. Examples to be used to illustrate these concepts include integrable equations of classical Hamiltonian mechanics as well as finite-dimensional models of the modern soliton theory such as the Toda lattice. If time permits, infinite dimensional examples (KP and KdV hierarchies) will also be considered.
