We use disk dia grams to also show that G is relatively hyperbolic to H. Basic definitions of small-cancellation theory and relative hyperbolicity will be covered i n the talk. This is a joint work with Daniel Wise.\n\n \n\nAs usual\, teat ime will follow the talk (this will also be our last teatime of the semest er).\n DTSTART:20241127T190000Z DTEND:20241127T200000Z LOCATION:Room 920\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:William Chong (ºÃÉ«TV) URL:/mathstat/channels/event/william-chong-mcgill-univ ersity-361451 END:VEVENT END:VCALENDAR
