Dynamical Systems (Winter Semester 2013/14)

  • Classes: Lecture (0105400), Problem class (0105500)
  • Weekly hours: 4+2

With the usage of computer power to numerically approximate solutions to ordinary and partial differential equations, the interest shifted from analytically calculating the exact solution to analyzing their (time-)asymptotic behavior. This is the starting point of the theory of dynamical systems.
A dynamical system is given by a rule, describing how a current state evolves with time. Typical examples are ordinary and (time-dependent) partial differential equations as well as their discretization. Note that time is continuous in the first two examples and discrete in the last one.
This lecture gives an introduction into the theory of finite and infinite dimensional systems. The main objective of the lecture is then to analyze the asymptotic behavior of solutions.
Topics include:

  • invariant sets and their stability properties (in the sense of Lyapunov)
  • stable and unstable manifolds
  • attractors
  • behavior of these objects under the change of a parameter or discretization (structural stability)

We plan to continue the analysis of dynamical systems by a lecture about traveling waves and their stability in the next semester.
