Many results and conjectures on the model involve the behavior of infinite geodesics: infinite paths whose finite subsegment s are geodesics for the FPP metric. In particular\, do doubly-infinite geo desics exist? Much progress has been made on this question when $d = 2$\, but the methods used there rely heavily on planarity. We will discuss new techniques which rule out a class of bigeodesics when $d > 2$ as well\, pr oviding the first results for general dimension. Based on joint works with G. Brito and M. Damron.\n DTSTART:20191113T200000Z DTEND:20191113T210000Z LOCATION:Room 1205\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Jack Hanson (City College of NY) URL:/mathstat/channels/event/jack-hanson-city-college- ny-302417 END:VEVENT END:VCALENDAR
