Topics
Dynamical Systems are concerned with anything that moves. Through the centuries, mathematical approaches take us on a fascinating voyage from origins in celestial mechanics to contemporary struggles between chaos and determinism.
The three semester course, aimed at graduate students in the framework of the Berlin Mathematical School, will be mathematical in emphasis. Talented and advanced undergraduates, however, are also welcome to this demanding course, as are students from the applied fields, who plan to really progress to the heart of the matter.
Here is an outline of the course:
Last semester
- Preliminaries: some calculus in Banach space
- Flows - differential equations - iterations
- Lyapunov functions and limit sets: the pessimism of decreasing energy
- Planar flows and Nietzsche's dwarf
This and next semesters
- Flows on tori and the "devil's staircase"
- Stable and unstable manifolds: what is a continental divide?
- Shift dynamics: coding "chaos"
- Hyperbolic structure and the "butterfly effect"
- Ergodicity: a static look at dynamics
- Shadowing: errors which don't matter
- Center manifolds: when hyperbolicity fails
- Singular perturbations: do differential-algebraic models make any sense?
- Normal form theory: let there be symmetry
- Averaging and "invisible chaos"
- The beauty of symmetry breaking
- A zoo of local bifurcations
- Genericity: to hell with mathematical degeneracy
- Takens embedding: dynamics without a model
- Global bifurcations and topological invariants
- Scientific Understanding of pictures
