General features of dynamical systems : Systems of differential equations with examples; control parameters; fixed points and their stability; phase space; linear stability analysis; numerical methods for nonlinear systems; properties of limit cycles; nonlinear oscillators and their applications; the impossibility of chaos in the phase plane; bifurcations: their classification and physical examples; spatial systems, pattern formation and the Turing mechanism; strange attractors and chaotic behaviour
  3. The logistic map: Linear and quadratic maps; graphical analysis of the logistic map; linear stability analysis and the existence of 2-cycles; numerical analysis of the logistic map; chaotic behaviour and the determination of the Lyapunov exponent; universality and the Feigenbaum numbers; other examples of iterated maps
  4. Hamiltonian Sytems: Phase space; Constants of motion and integrable Hamiltonians; Nonintegrable systems, the KAM theorem and period-doubling; applications
  5. Fractal geometry: dimension of an object, Mandelbrot set, Julia set, iterated function systems
  6. Spatio-temporal dynamics: Spatio-temporal chaos
  7. Quantum Chaos: Quantum analogies to Chaotic behaviour, Correaltions in wave functions, chaos and Semi-classical approaches to Quantum mechanics
