CANCELLED 2019/20: Dynamical Systems

Course content

The course is an introduction to dynamical systems with emphasis on Ordinary Differential Equations (ODEs). The following topics will be discussed:

  • Linear Systems: Existence and Uniqueness Theorem, Continuous Dependence on Initial Conditions and Parameters
  • Stability Theory: Matrix solutions, Lyapunov functions
  • Global Theory of Nonlinear Systems: Hartman-Grobman Theorem, Poincare-Bendixson Theorem
  • Bifurcation theory: One and two dimensional bifurcations
  • Discrete Dynamical Systems: Period doubling bifurcation
  • Applications to chemistry, ecology, epidemiology and mechanics.

Learning outcome

Knowlegde:

  • Basic concepts in dynamic system theory: solutions, stability, bifurcation. 
  • Standard methodes to determine the behavior of a dynamical system: Lyapunov function approach, eigenvalues of coefficient matrix
  • Local versus global behavior.

 

Skills:

  • Solve 2- and 3-dimensional linear ODEs with constant coefficients
  • Determine uniform / asymptotic stability of equilibria for linear systems 
  • Prove stability / instability of gradient systems by constructing Lyapunov functions
  • Compute stable / unstable manifolds of simple 2-3 dimensional nonlinear systems
  • Identify fixed-point bifurcations and Hopf bifurcation for 1 or 2-dimensional ODEs 
  • Describe bifurcations for simple discrete mappings

 

Competences:

  • Apply dynamical systems theory to build models and understand natural phenomena (for instance, Hopf bifurcation)

4 hours lectures and 2 hours exercises per week for 7 weeks.
