# Dual Legendrian Variations in Contact Form Geometry

 GEOMETRIC PDE SEMINAR Topic: Dual Legendrian Variations in Contact Form Geometry Speaker: Abbas Bahri Affiliation: Rutgers University Date: Tuesday, December 9 Time/Room: 1:30pm - 3:30pm/S-101

In 1979, in collaboration with D. Bennequin, we started a direction of research around the study of periodic trajectories of the Reeb vector field $\xi$ on a contact manifold $(M^3, \alpha)$. We will describe in this talk where this direction of research stands as of today.
