Presentation of the Laboratoire Analyse, Géométrie et Applications

The Laboratoire Analyse, Géométrie et Applications (usually abbreviated to LAGA) is a research "laboratory" (UMR 7539) associated to the CNRS, the Centre National de la Recherche Scientifique. It is attached to the Institut Galilée, which is a component of the Université Paris 13, and also to the Université Paris 8.

The research group is made up of about seventy research mathematicians (twelve of whom hold CNRS research positions), seven administrative staff and more than thirty PhD students. In addition, the department acts as a host instution for a number of post-doctoral students and frequently invites guests from abroad (a list of of past visitors is available).

The principal areas of research which are currently pursued at LAGA are the following:

Algebraic geometry, algebraic topology, arithmetic geometry, category theory, dynamical systems, ergodic theory, error correcting codes and cryptography, harmonic analysis, image processing, homotopy theory, linear and non-linear partial differential equations, mathematical physics, micro-local analysis, number theory, numerical analysis, probability, representation theory, spectral theory, stochastic analysis, statistics.

The director of LAGA is Laurence Halpern; the laboratory is comprised of seven research groups, each with its own director:

• Arithmetic and algebraic geometry (Jacques Tilouine)
• Algebraic topology (Bob Oliver)
• Ergodic theory and dynamical systems (François Parreau)
• Mathematics for information and image processing (Claude Carlet, Françoise Dibos)
• Modelling and Analysis (Frederic Weissler)
• Mathematical Physics and partial differential equations (Jean-Marc Delort)
• Probability theory and Statistics (Yueyun Hu).

The laboratory LAGA has a research library and preprints by members of the LAGA are available on the French preprint server HAL. LAGA organizes a number of regular and occasional seminars, in addition to working-groups; it has also hosted a number of conferences.

LAGA aims to provide a solid research base for its doctoral students, who may have obtained their Master at any of the Paris universities. In particular it takes students who have obtained the Master "fundamental mathematics" (Paris 13) and the Master "numerical analysis".
