We agreed about the times for the seminars and the lectures as indicated below.
|
|
I updated problem 3 of problem set 1 to account for the fact that the centrifugal governor was not treated in class.
More details are given in the wiki,
where I also provide
discussion pages for the exercises.
Please contact me if you have are no account for the wiki.

We will have our first lectures on 13 April 2021 at 15:00 in
BBB
(no access code required).
|
Dynamical Systems. |
characterization of flows, critical points, stability |
|
bifurcations, normal forms, center manifolds |
|
chaos, routes to chaos, symbolic dynamics |
| |
Fractals. |
fractal dimensions, multifractals, thermodynamic formalism |
|
diffusion limited aggregation, snow flakes, breath figures |
| |
Pattern Formation. |
linear and non-linear stability |
|
multiscale analysis, amplitude equations, Eckhaus and Benjamin-Feir instabilities |
|
hydrodynamic systems, nonlinear waves, turbulence |
|
reaction-diffusion systems, Turing instabilities |
I will use
Python and Sage for numerical studies and visualization.
The script files are notebooks that run interactively in Jupyter.
Please store them on your computer, start Jupyter, and then open the notebook.
The files contain absolutely minimalistic explanations and comments.
I assume that you know what they are intended to do because we discussed the problems in class.
As introductions to Python and Sage I recommend the books
Steward: "Python for Scientists"
and
Zimmermann u.a.: "Computational Mathematics with SageMath".
