Bf.38 Chaos and Nonlinear Physics

Bf.38 Chaos and Nonlinear Physics

Contents
In this course we attempt to give an introduction to chaos and nonlinear physics in a variety of physical systems. We begin with a qualitative discussion of turbulence in fluids and then move on to the Lorenz equations for atmospheric turbulence, phase space descriptions, attractors, Lyapunov exponents characterizing chaos, etc. Next we discuss nonlinear dynamics in terms of simple maps and discuss the Feigenbaum theory for universal periode doubling. At the end of the course we also try to briefly discuss intermittency, quasiperiodicity, and chaos in Hamiltonian systems.
