报告摘要：

Legendrian knots and their exact Lagrangian fillings are central objects to study in low dimensional contact and symplectic topology. Exact Lagrangian fillings are generally difficult to construct and to distinguish. Recent development indicates that a Legendrian knot could carry infinitely many exact Lagrangian fillings, and this phenomenon is abundant. In this talk, I will focus on the first such examples, which is a joint work with Roger Casals.
