DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SRS/14/">Geo
 desics and Laplace spectrum on 3D contact sub-Riemannian manifolds: the Re
 eb flow</a>\nby Yves Colin de Verdière (Institut Fourier) as part of Sub-
 Riemannian Seminars\n\n\nAbstract\nJoint work with Luc Hillairet (Orléans
 ) and Emmanuel Trélat (Paris).\nA 3D  closed manifold with a contact dist
 ribution  and a  metric on it carries a canonical contact form. The associ
 ated Reeb flow plays a central role  for the asymptotics of the geodesics 
 and for the spectral asymptotics of the Laplace operator. I plan to descri
 be it using some Birkhoff normal forms.\n
