The Abdus Salam International Centre for Theoretical Physics (ICTP) is orgamzing a "Fifth International Conference and School Geometry, Dynamics, Integrable Systems - GDIS 2014: Bicentennial of The Great Poncelet Theorem and Billiard Dynamics", to be held at ICTP, Trieste, Italy, from 16 June to 27 June 2014. The main aim of the school is to introduce young participants into these exciting topics and prepare them for the week long conference to follow the school. The first week on the activity is devoted to a school that will give an overview of recent developments and interrelations between geometry and dynamical systems, with a special focus on mathematical billiards and integrable systems. The school will provide a background in algebraic geometry, theory of measured foliations and flat surfaces, the discrete integrable systems, 2-2 correspondences, the QR T maps, and the mechanical background of the billiard systems. The second week will be an international conference, where leading experts will report on the newest developments in the field of integrable dynamical systems and their geometry. The event will mark the bicentennial of the great Poncelet theorem.
