The subject of dynamical systems is truly interdisciplinary, and its concepts and methods are currently used in all fields of science, such as physics, engineering, chemistry, biology, physiology, economics, and sociology. Therefore, the module should be interesting not only to mathematicians, but also to physicists, engineers, chemists and everybody interested in the subject.
One-dimensional maps. Fixed points, periodic orbits and their stability. Piecewise linear maps. Symbolic dynamics. Logistic map. Bifurcations. Universal scaling of period doubling bifurcations in quadratic maps. Other types of bifurcations in one-dimensional maps. Measure, ergodicity and Lyapunov exponents for one-dimensional maps.
Strange attractors and fractal sets. Cantor set. Lebesgue measure. Box-counting dimension. Generalised baker's map. Natural measure and dimension spectrum. Determination of fractal dimension in experiments. Embedding.
Horseshoe map and symbolic dynamics. Linear stability analysis. Invariant subspaces and manifolds. Homoclinic and heteroclinic intersections. Lyapunov spectrum. Metric and topological entropies.
Quasiperiodicity. Circle map. Arnold tongues. Hopf bifurcation. Hamiltonian systems. Symplectic structure. Canonical transformations. Integrable systems. Perturbation of integrable systems. KAM (Kolmogorov-Arnold-Moser) theorem. Resonant tori. Chaotic transitions. Intermittency. Crises.
