DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SeedSeminar/
 124/">Graphical calculus for twisted pivotal categories</a>\nby Benjamin H
 aïoun (University of Edinburgh) as part of Seed Seminar of Mathematics an
 d Physics\n\n\nAbstract\nGraphical calculus provides a convenient way to r
 epresent objects and morphisms in a monoidal category using strands in the
  plane. This viewpoint extends naturally to more general surfaces and lead
 s to constructions of TQFTs\, such as the Turaev–Viro theories. In order
  to obtain oriented TQFTs\, one usually uses a pivotal structure. In this 
 talk\, I will describe a more general approach based on a twisted pivotal 
 structure\, as predicted by the cobordism hypothesis. I will introduce a g
 raphical calculus for these structures\, which involves foliated surfaces 
 and many drawings.\n
