SMRI Seminar: Donovan -- McKay correspondence and toric geometry

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.
