Many nonlinear ODEs do not have explicit solutions. The dynamical systems approach shifts the focus from finding explicit solutions to discovering geometric properties of solutions. It also recognises that even a small amount of nonlinearity in a physical system can be responsible for very complicated chaotic behaviour.
In this course you will learn the fundamentals of dynamical systems in (continuous time) nonlinear ODEs and in (discrete time) nonlinear maps, allowing you to analyse the local and global behaviour of nonlinear systems.
Nonlinear maps: The building blocks of dynamics
Fixed points, periodic points, invariant sets, recurrence, nonwandering sets, symbolic dynamics, conjugacy, sensitive dependence on initial conditions, Lyapunov exponents, fractals, Stable Manifold Theorem, chaotic attractors, Smale's Horseshoe, ergodic theory.
Nonlinear ODEs: A geometric, qualitative approach to ODEs
Phase portraits, fixed points, periodic and chaotic trajectories, sources, sinks, and saddles, stable and unstable subspaces, robustness, hyperbolicity, stability, conjugacy, stable and unstable manifolds, bifurcations.
