Using Pho-On's infinite unicorn pat hs\, we prove hyperfiniteness of the orbit equivalence relation coming fro m the action of the mapping class group of S on the Gromov boundary of the arc graph of S. This is joint work with Marcin Sabok.\n\nLink: https://mc gill.zoom.us/j/98910726246?pwd=VHlzTzdTZGtqcHVuWGNKdys4d0FzQT09\n\nZoom ID : 989 1072 6246\n Password: delta\n DTSTART:20201118T200000Z DTEND:20201118T210000Z SUMMARY:Piotr Przytycki (Âé¶¹´«Ã½ÍøÕ¾) URL:/mathstat/channels/event/piotr-przytycki-mcgill-un iversity-326272 END:VEVENT END:VCALENDAR
