With the n otion of micro-support\, one can use sheaves on smooth manifolds to access the geometry of their cotangent bundles. In recent years\, microlocal she af theory entered contact and symplectic topology\, and has been used to s olve open problems. In this lecture series\, we will introduce microlocal sheaf theory in the context of low-dimensional contact topology\, and supp ly the audience with background for its applications such as producing non -classical invariants for Legendrian knots and distinguishing exact Lagran gian fillings.\n\nLecture 2: invariance $\\newline$\nCategory of sheaves\, non-classical invariants for Legendrian submanifolds (theorem by Guillerm ou-Kashiwara-Schapira)\, combinatorial verification under Reidemeister mov es.\n LOCATION:https://researchseminars.org/talk/LCM2021/2/ END:VEVENT END:VCALENDAR
