With the no tion of micro-support\, one can use sheaves on smooth manifolds to access the geometry of their cotangent bundles. In recent years\, microlocal shea f theory entered contact and symplectic topology\, and has been used to so lve open problems. In this lecture series\, we will introduce microlocal s heaf theory in the context of low-dimensional contact topology\, and suppl y the audience with background for its applications such as producing non- classical invariants for Legendrian knots and distinguishing exact Lagrang ian fillings.\n\nLecture 1: Legendrian knots and sheaves $\\newline$\nBasi cs of Legendrain knots\, sheaves and microsupport\, local conditions at ar cs\, cusps\, crossings.\n LOCATION:https://researchseminars.org/talk/LCM2021/1/ END:VEVENT END:VCALENDAR
