Thus, lectures will be devoted to current topics in bifurcation theory, Abelian integrals, control on the number of periodic orbits, Hilbert 16th problem, oscillations of the time function, Abel equations, integrability and related topics. It is planned the participation of around 50 researchers. The event aims to create a relaxed atmosphere, with few lectures and free time between them for fruitful discussions. In few days we will update the information in the web page of the conference about conference fee, deadlines for poster submissions, payments, accommodation hotels,... Then you will receive a second announcement.

The next Equadiff conference will take place from July 6 to 10, 2015 at the University of Lyon, France. Please consult the website http://equadiff2015.sciencesconf.org/ for up-to-date information. Registration is already open. CONTRIBUTED TALKS: A limited number of slots are available for contributed talks (25' + questions). Interested people should submit their abstract on the conference's website before MARCH 30, 2015 Acceptation will be notified by April 30, 2015. EARLY BIRD FEES: For all participants, early bird registration fees are available until MAY 30, 2015. We are looking forward to seeing you in Lyon! For the organizing committee, Sylvie Benzoni-Gavage Thierry Gallay ------ Subject: Course in numerical bifurcation analysis and its application From: Thomas Lorenz Date: Thu, 29 Jan 2015 21:53:23 +0100 At RheinMain University of Applied Sciences in Wiesbaden (Germany), the degree programme "Applied Mathematics" (M.Sc.) offers a compact course in "Numerical bifurcation analysis and its application" under the direction of Prof. Jens Starke (Technical University of Denmark, Kongens Lyngby, DK). It will take place at RheinMain University of Applied Sciences (Building C) Kurt-Schumacher-Ring 18 65197 Wiesbaden (Germany) from Monday, March 30, 2015 till Thursday, April 2, 2015. This compact course in English provides an introduction to bifurcation theory with special emphasis on the numerical approaches and their application to concrete problems. It starts from a rather elementary level and then focuses on the key steps to the state-of-art in bifurcation analysis. Standard numerical algorithms are adapted for detecting first stationary points of ordinary differential equations (ODEs) and then periodic orbits of ODEs. The focus is on continuation methods using predictor corrector algorithms. Exercises will be organized so that the participants can gain their own experience in implementing and applying the methods to concrete applications in mechanics, for example. Master students from other institutions are cordially welcome.
