Northern California Symplectic Geometry Seminar: The Legendrian topology of surface triangulations

Seminar | November 6 | 2:30-3:30 p.m. | Stanford University, Room 384H

 Roger Casals, MIT and UCL

 Department of Mathematics

In this talk I will introduce a class of Legendrian wavefronts associated to surface triangulations. First, I will explain the interplay between the Legendrian isotopy type and the combinatorics of the triangulation. In particular, we will be connecting symplectic geometry and graph theory. Then I will discuss the Floer theory of these wavefronts and provide a description of their dg-algebras. The talk will conclude with two geometric applications.
