Original Announcement

This workshop will be devoted to the study of the behavior of geodesics in the large. Although this is an old subject, with important contributions first made by J. Hadamard and H. Poincare, many of the fundamental problems are still open.

The study of geodesics is a central part of Riemannian geometry, of the calculus of variations and of Hamiltonian dynamics. Beyond that it is related to a remarkably large number of mathematical and non-mathematical fields ranging from the study of PDEs to number theory and from transport problems to general relativity. So it is no surprise that often progress in geodesic problems is achieved by combining ideas and methods from different areas.

The workshop will stimulate exchange and cooperation between researchers from diverse mathematical fields with interest in geodesics.

Here is a non-exhaustive list of topics to be discussed in the workshop.
