How many lines through the origin pairwise separated by the s ame angle can be placed in 3-dimensional space? What about higher-dimensio ns?\n\nThese extremal problems in Discrete Geometry look deceitfully simpl e\, yet some of them remain unsolved for an extended period or have been p artly solved only recently following great efforts. In this talk\, I will discuss two longstanding problems: Fejes Tóth’s zone conjecture and a prob lem on equiangular lines with a fixed angle.\n\nNo specific background wil l be needed to enjoy the talk.\n DTSTART:20200204T203000Z DTEND:20200204T213000Z LOCATION:Room 708\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Zilin Jiang (MIT) URL:/mathstat/channels/event/zilin-jiang-mit-303864 END:VEVENT END:VCALENDAR
