We g ive a brief overview of the results in Euclidean space then talk about the unexpected behavior of the fundamental gap in hyperbolic space. We presen t two types of questions related to the fundamental gap: the first type\, which deals with bounding the gap from below has received a lot of attenti on\; the second type is about the optimality of the constant potential. We found recently that the constant potential is not the one that provides t he best lower bound.\n DTSTART:20260522T150000Z DTEND:20260522T160000Z LOCATION:Room 1104\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Xuan Hien Nguyen (Iowa State University) URL:/mathstat/channels/event/xuan-hien-nguyen-iowa-sta te-university-372977 END:VEVENT END:VCALENDAR
