273027 Introduction to Dynamical Systems 2012 (5 sp)

The course treats fundamental notions in the theory of discrete-time dynamical systems, such as periodicity, attraction/repulsion, bifurcations, chaos and sensitive dependence on initial conditions ("the butterfly effect"). In the multidimensional case we give a survey of classical stability theory for linear systems.

The course in given, in English or Swedish depending on the audience, by professor Göran Högnäs on Mondays 10-12 in aud. Vectorrummet, Tuesdays 13-15 and Fridays 13-15 in aud. Hilbertrummet B329 on the 3rd floor of the ASA building.

The course starts on Monday, January 9 at 1 p.m. and ends on Friday, March 9. There are weekly exercise sessions, but in addition some larger individual project work will also be assigned. The examination is a 24-hour open-book examination. Preliminary examination date is Thursday-Friday, March 8-9.
