DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QGS/85/">Top
 ological order\, tensor networks and subfactors</a>\nby Yasuyuki Kawahigas
 hi (University of Tokyo\, Japan) as part of Quantum Groups Seminar [QGS]\n
 \n\nAbstract\nI will explain interactions between two-dimensional topologi
 cal order and subfactors from a viewpoint of tensor networks.  The range o
 f a certain finite dimensional projection appearing in statistical physics
  is identified with the higher relative commutant of the subfactor arising
  from such a tensor network.  We then work out the machinery of alpha-indu
 ction\nfor braided fusion categories in the setting of certain 4-tensors\,
  called bi-unitary connections\, appearing in subfactor theory.\n
