Course Aim
It is well known that all physical systems (except in quantum mechanics) are nonlinear. Former limitations to linear systems was of practical nature, as they generally were the only ones which could be exactly solved. By working with user-friendly computer software like Maple the knowledge gained can be applied to problems that would be impossible to study by "paper and pen alone".
To teach basic methods of nonlinear physics, which the student can use in his/her continued education, reserch of future work.

1. The world - a nonlinear system!
2. Introduction to Maple
3. Modelling Nature
4. Nonlinear systems I: Examples from a) Mechanics, b) Population dynamics, c) Electrical circuits, d) Chemical osillations, e) Heartbeats
5. Nonlinear systems II: a) Structure formation, b) Solitons, c) Chaos
6. Topological analysis: a) Singular points, b) Phase-plane analysis, c) Bifurcations
7. Limit-cycles: a) Stability, b) Mathematical theorems
8. Forced oscillations: a) Examples, b) Chaotic oscillations, c)"Strange attractors" d) Chaos in Hamiltonian system
9. Nonlinear mapping: a) Logistic mapping, b) Fix-points and stability, c) Period doubling towards chaos, d) The Lyapunov exponent, e) 2-and 3-dimensional mappings, f) Chaos control
10. Nonlinear partial differential equations: a) Examples, b) Nonlinear superposition, c)Solitary waves d) Numerical simultation, e) Inverse scattering method, f) Solitons
