DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MathPic/143/
 ">Tensor networks\, fusion categories and operator algebras</a>\nby Yasuyu
 ki Kawahigashi (University of Tokyo/RIKEN) as part of Mathematical Picture
  Language Seminar\n\nLecture held in Jefferson 368.\n\nAbstract\nCertain 4
 -tensors have been used to study two-dimensional topological order\, and w
 e identified them with bi-unitary connections in subfactor theory of Jones
  before.  This identification gives a description of a fusion category usi
 ng a (possibly non-flat) bi-unitary connection\, which arises as quantum 6
 j-symbols for a multi-fusion category.  We further advance this identifica
 tion by working on the zipper condition\, which is a kind of pentagon equa
 tion\, and flat fields of strings.\n\nPasscode: 657361\n
