DESCRIPTION:We show how a diagrammatic calculus for spherical fusion categ
 ories\, bimodule categories with bimodule traces and bimodule functors and
  bimodule natural transformations can be used to define state sum invarian
 ts for 3-manifolds with defects that generalise the usual Turaev-Viro-Barr
 ett-Westbury state sum invariants of 3-manifolds.Reference:C. Meusburger\,
