Youngjin Bae from Incheon National University will be speaking.
The title is "Legendrian graphs and their invariants".
Contact Honghao Gao (email@example.com) for more information.
Legendrian graphs naturally appear in the study of Weinstein manifolds with a singular Lagrangian skeleton, and a tangle decomposition of Legendrian submanifolds. I will introduce various invariants of Legendrian graphs including DGA type, polynomial type, sheaf theoretic one, and their relationship. This is joint work with Byunghee An, and partially with Tamas Kalman and Tao Su.
