Numerics of Dynamical Systems (MA3333)
Prof. Dr. Oliver Junge,
Michael Kratzer
Content
Dynamical Systems are mathematical models of systems which change their state with time. Typical examples are (certain) ordinary or partial differential equations. A basic question for a such system is of course to compute its temporal evolution, given a particular initial condition, i.e. to
simulate the system.
Often, however, one is interested in the targeted computation of particular solutions, e.g. equilibrium points (i.e. states which do not change with time), periodic solutions or connecting orbits. In addition, many models from applications exhibit
complicated dynamics. Here, the questions is how one can describe the dynamics of such systems over long time spans and how these descriptions can be reliably approximated numerically. These are questions which are being treated in this lecture, tying in with MA 3082
Nonlinear Dynamics.
