I will discuss how many exact Lagrangian fillings of Legendrian torus knots are possible up to Hamiltonian isotopies.

The main tools are augmentations of Legendrian DGA and Lagrangian saddle cobordisms.

I will also talk about how the cluster structure and Dynkin diagrams are related to this subject.

This is a joint work in progress with Byunghee An.

Lecture 1: Legendrian knot, Legendrian DGA.

Lecture 2: Lagrangian saddle cobordism and DGA map.
