Augmentations and sheaves for knot conormals
Vendredi, 28 Septembre, 2018 - 10:30
Résumé : 

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. The Nadler-Zaslow correspondence suggests a connection between the two types of invariants. In this talk, I will manifest this correspondence explicitly for knot conormals.
