Course contents
Intended learning outcomes
After the course the student should be able to:
- Explain how ordinary differential equations (ODE) and iterated maps give rise to dynamical system.
- Be able to define the state space, its limit sets and attractors.
- Explain how the state space dimension limits the possible dynamics.
- Sketch the limit set and starting from this characterize the main features in the flow of a dynamical system given by ODEs in the plane.
- Recognize and describe the result of a simulation using the concept of Poincare mapping.
- Know about and be able to calculate the fractal dimension in a few simple cases.
- Know about the concept of chaos in dynamical systems and state some properties of a chaotic dynamical system.

Ethical approach
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
