Sub-Riemannian geometry on the group of motions of the plane

29-Jan-2021, 15:00-16:00 (4 years ago)

Abstract: We will discuss the unique, up to local isometries, contact sub-Riemannian structure on the group SE(2) of proper motions of the plane (aka group of rototranslations). The following questions will be addressed: - geodesics, - their local and global optimality, - cut time, cut locus, and spheres, - infinite geodesics, - bicycle transform and relation of geodesics with Euler elasticae, - group of isometries and homogeneous geodesics, - applications to imaging and robotics.

Sub-Riemannian Seminars

Series comments: The "Sub-Riemannian seminars" are the union of the "Séminaire de géométrie et analyse sous-riemannienne" (held in Paris since 2011) and the "International Sub-Riemannian Seminars", which were born in spring 2020 as a reaction to the COVID-19 pandemic.

The new format will gather every 3 weeks on average, alternating between these types of sessions:

- physical session in Paris (Laboratoire Jacques-Louis Lions), also transmitted online on Zoom.

- fully online session on Zoom.

- special session hosted physically somewhere else, and transmitted online.

Organizers: Ugo Boscain, Enrico Le Donne, Luca Rizzi*, Mario Sigalotti, Emmanuel Trelat
