Moreover\, I will describe a generalization to higher dimension s of a classical result of Goldman which says that the Goldman Lie algebra of free loops on a surface acts by Hamiltonian vector fields on the chara cter variety of the surface. A key input is a description of deformations of Calabi-Yau structures\, which is of independent interest. This is joint work with Chris Brav.\n\nLocation: UQAM PK-5675\n DTSTART:20251029T180000Z DTEND:20251029T190000Z SUMMARY:Nick Rozenblyum (Toronto) URL:/smerg/channels/event/nick-rozenblyum-toronto-3685 86 END:VEVENT END:VCALENDAR
