DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SympZoominar
 /188/">$C^0$-rigidity in contact topology via microlocal sheaf theory</a>\
 nby Wenyuan Li (USC) as part of Symplectic zoominar\n\n\nAbstract\nContact
  homeomorphisms are points in the closure of the (compactly supported) con
 tactomorphism group in the homeomorphism group under the $C^0$-topology. R
 ecently\, Dimitroglou Rizell and Sullivan showed that the images of closed
  Legendrians under contact homeomorphisms are still Legendrian if they are
  smooth. One can ask further questions: (1) whether images of coisotropics
  are still coisotropic if they are smooth\, and (2) whether Maslov data an
 d Floer theory invariants of closed Legendrians are preserved. We provide 
 an approach of understanding such questions in cosphere bundles (with the 
 standard contact structures) using microlocal sheaf theory. This is joint 
 work with Tomohiro Asano\, Yuichi Ike and Christopher Kuo.\n
