SUMMARY:3d N=2 gauge theories on Seifert manifolds (or: how to localise on
  the Poincaré sphere) - Cyril Closset (CERN)

CONTACT:Dr. Carl Turner
DESCRIPTION:Much new insight about the dynamics of supersymmetric theories
  in three space-time dimensions has been obtained thanks to exact\, non-pe
 rturbative results for supersymmetry-protected observables\, including the
  so-called supersymmetric partition functions. In this talk\, I will discu
 ss new results for the supersymmetric partition function of 3d N=2 gauge t
 heories on any (orientable) Seifert three-manifold. I will explain how all
  these supersymmetric partition functions (including the familiar three-sp
 here) are related to each other\, and can be thought of as expectation val
 ues of some defect line operators in a 3d twisted chiral ring.
