Title: Augmentations and sheaves for knot conormals

Speaker: Honghao Gao (Institut Fourier)

Abstract: Knot invariants can be defined using Legendrian isotopy invariants of the knot conormal. There are two types of invariants raised in this way: one is the knot contact differential graded algebra together with augmentations associated to this dga, and the other one is the category of simple sheaves microsupported along the knot conormal. Nadler-Zaslow correspondence suggests a connection between the two types of invariants. In this talk, I will manifest this correspondence, explicitly at the level of objects.
