Augmentations and sheaves for links

Vendredi 17 mai 2019 15:30-16:30 - Honghao Gao - Grenoble

Résumé : We study two different invariants of framed oriented links. Augmentations are rank one representations of a non-commutative algebra, whose definition is motivated by Floer homology. Sheaves in microlocal theory can be thought of as generalizations of link group representations. We will demonstrate two constructions going back and forth between these invariants. We will also tell a motivating story behind the scene, using SFT and microlocalization correspondence in symplectic topology.

Lieu : Salle 3L8
