SMRI Seminar: ’McKay correspondence and toric geometry’ Will Donovan (Tsinghua University) Date and time: Thursday 11 April, 13:00-14:00 AEST Location: Law Annex Lecture Theatre 026 (in person only) Abstract: Finite subgroups of the matrix group SU(2) may be studied algebraically via their representations. They may also be studied geometrically via two-dimensional complex manifolds naturally associated to them. The McKay correspondence is a general phenomenon which, in particular, explains how these two approaches relate. I’ll introduce this using diagramatics from toric geometry, indicate how the correspondence generalizes to higher dimensions, and discuss open questions and current projects. ---- Please join us after the seminar for SMRI afternoon tea, 2:00-2:45pm every Thursday on the SMRI Terrace (accessed through A14-04-L4.36) ---- Current and past seminar info (including recordings) can be found on the seminars webpage.
