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. Tent map. Fixed points, periodic orbits and their stability. Bifurcations. Logistic map. 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. Natural measure and dimension spectrum.
Linear stability analysis. Invariant subspaces and manifolds. Homoclinic and heteroclinic intersections. Lyapunov spectrum. Metric and topological entropies.
Hamiltonian systems. Symplectic structure. Canonical transformations. Integrable systems. Perturbation of integrable systems. The KAM theorem. Resonant tori. Strongly chaotic systems. Classification of increasingly random systems.
Chaotic transitions. Intermittency. Crises.
