I will briefly explain its construction and descri be its classification in terms of immersed curves on a 4-punctured sphere as well as a glueing formula. Finally\, I will discuss some applications\, such as rational tangle detection\, skein relations and mutation symmetri es.\n DTSTART:20171027T150000Z DTEND:20171027T160000Z LOCATION:Room PK-5115 \, CA\, Pavillon President-Kennedy SUMMARY:Claudius Zibrowius\, Université de Sherbrooke URL:/mathstat/channels/event/claudius-zibrowius-univer site-de-sherbrooke-279854 END:VEVENT END:VCALENDAR
