Abstract
Legendrian knots and their exact Lagrangian filings are center of the low dimensional contact and symplectic topology. They can be used to classify 3‐dimensional contact structures and 4‐dimensional Weinstein manifolds. In this talk, I will explain the geometric construction of exact Lagrangian fillings and the algebraic machinery to distinguish them. This is a joint work with Roger Casals.
