For example\, such varieties of dimension 2 are Klei nian singularities. Starting from this\, I will describe a combinatorial a pproach to classifying the next case\, affine quiver varieties of dimensio n 4. If time permits\, I will try to say the implications we obtained and how can one compute the number of crepant symplectic resolutions of these varieties. This is a joint project with Samuel Lewis.\n\nLocation: UQAM PK -5675\n DTSTART:20250528T180000Z DTEND:20250528T190000Z SUMMARY:Pavel Shlykov (Edinburgh) URL:/mathstat/channels/event/pavel-shlykov-edinburgh-3 65525 END:VEVENT END:VCALENDAR
