DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TRAC/5/">The
  cluster category of a Postnikov diagram</a>\nby Matthew Pressland as part
  of The TRAC Seminar - Théorie de Représentations et ses Applications et
  Connections\n\n\nAbstract\nA Postnikov diagram consists of a collection o
 f strands in the disc\, with combinatorial restrictions on their crossings
 . Such diagrams were used by Postnikov and others to study weakly separate
 d collections in certain matroids called positroids. In this talk I will e
 xplain how the diagram determines a cluster algebra structure on a suitabl
 e subvariety of the Grassmannian\, and simultaneously provides a (Frobeniu
 s) categorification of this cluster algebra.\n
