DESCRIPTION:Title: <a href="https://researchseminars.org/talk/WiSe/18/">Wh
 at is a hyperpolygon?</a>\nby Steven Rayan (University of Saskatchewan) as
  part of What is ...? Seminar\n\n\nAbstract\nHyperpolygons are geometric o
 bjects originating in representation theory and\, in particular\, act as a
  bridge between a number of important geometric and representation-theoret
 ic moduli spaces.  Given this role\, hyperpolygons interact naturally with
  a number of other notions that have been presented in this series\, inclu
 ding Higgs bundles\, character varieties\, hyperkähler geometry\, nonabel
 ian Hodge theory\, integrable systems\, mirror symmetry\, and Coulomb bran
 ches\, to name a few.   In the first part of the talk\, we will review the
  construction of a Nakajima quiver variety\, of which hyperpolygon space i
 s a particular instance.   In the second half of the talk\, we will focus 
 on the connections that hyperpolygons have with the various other notions 
 from this series\, which include a number of recent\, interesting results.
