DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MathPic/116/
 ">On Quantum Symmetry</a>\nby David Evans (Cardiff University) as part of 
 Mathematical Picture Language Seminar\n\nLecture held in Jefferson 453.\n\
 nAbstract\nThis talk is part of a programme to understand quantum symmetri
 es and conformal field theory through subfactors  and K-theory\, in partic
 ular twisted equivariant K-theory. Freed\, Hopkins and Teleman realized th
 e Verlinde fusion ring of positive energy representations of loop groups t
 hrough twisted equivariant K-theory of the section algebra of equivariant 
 bundles of compact operators. This raised the possibility of studying such
  fusion rings or quantum symmetries as modules and bimodules for certain C
 *-algebras  as well as introducing higher twists through equivariant bundl
 es beyond those of compact operators. This has been pursued in work with T
 erry Gannon\, Andreas Aaserud\, Ulrich Pennig and Corey Jones.\n
