Lyapunov analysis, from theory to geophysical applications
26-30 October 2009
Institute of Complex Systems, Rue Lhomond 57-59, 75005, Paris France
Lyapunov exponents and vectors provide a powerful theoretical and practical framework for the analysis of the instabilities that can develop in a dynamical system. This Thematic Institute, to take place at the Institute of Complex Systems, Paris on October 26th-30th aims at bringing together scientists active in applied mathematics and/or geophysics, finding the crossing point between state-of-the-art Lyapunov analysis theory and the current challenges faced by geophysics. Special emphasis will be put on recent theoretical results on Lyapunov vector analysis, turbulent transport, and data assimilation.
The Institute will be organized around introductory perspective lectures (3-4 hours each) given by leading experts, covering both the theoretical and application aspects. These lectures will be complemented by shorter seminars presented by the participants and by plenary and informal discussions. Participants are not required to have experience in both theory and geophysical applications of Lyapunov exponent analysis, although at least some general knowledge in one of the two fields is expected.

Programme
Keynote lectures are in the morning. The first part of the afternoon (between lunch and 16.00) is devoted to discussions in either plenary sessions or parallel working groups. Between 16.00 and 18.00 there will be the additional contributions from the participants. This meeting will also be the occasion for celebrating the 65th birthday of Michael Ghil.9h00 Welcome
