b-Structures are hidden in many places, in the boundary of manifolds and index formulae (Melrose, Nest-Tsygan), in the geometry of pseudo-Riemannian geodesics (Khesin-Tabachnikov) and in the regularization transformations in celestial mechanics (Mc Gehee). We will give a panorama talk on b-structures in the symplectic and contact realm describing some of the main techniques and some open problems.
The talk will be via Zoom at:
