We define a metrically systol ic complex as flag simplicial complex with a given metric on their two-ske leton satisfying some local conditions. I will present few features of suc h complexes resembling the ones of non-positively curved spaces. Then I wi ll talk about two-dimensional Artin groups\, metrically systolic complexes they act on\, and consequences of admitting such actions. One of them is solvability of the conjugacy problem for Artin groups in question and for all their finitely presented subgroups.\n DTSTART:20180905T190000Z DTEND:20180905T200000Z LOCATION:Room 1104\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Damian Osajda (University of Wrocław) URL:/mathstat/channels/event/damian-osajda-university- wroclaw-289213 END:VEVENT END:VCALENDAR
