DESCRIPTION:Title: <a href="https://researchseminars.org/talk/EQuAL/28/">G
 ray categories with duals and their diagrams</a>\nby John Barrett (Univers
 ity of Nottingham) as part of European Quantum Algebra Lectures (EQuAL)\n\
 n\nAbstract\nGray categories with a coherent notion of duals are captured 
 well by a calculus of three-dimensional diagrams\, generalising the famili
 ar string diagrams for braided categories. The talk will discuss what is i
 n the paper with this title (Advances in Mathematics\, Volume 450\, 2024\,
  109740)\, what got left out\, and what is still missing.\n
