Algebra Seminar: Simpson -- Reflections on tori

Connor Simpson (University of Sydney) will be speaking in the algebra seminar.  We will
go out for lunch after the talk---all are welcome to join! 

When: 12-1pm Friday October 17 

Where: SMRI Seminar Room (Macleay Building A12 Room 301) [ROOM CHANGE DUE TO BOARD TALK] 

Title: Reflections on tori 

Abstract: Toric varieties are a rich, yet tractable class of spaces, whose geometry can
be understood via the combinatorics of polytopes.  We'll give an introduction to these
spaces from the algebreo-geometric and topological viewpoints, then explain some recent
work that describes quotients of toric varieties by finite reflection groups (joint with
Colin Crowley & Tao Gong).
