SUMMARY:Singular Hecke categories and thick KLR  diagrammatics - Amit Hazi
  (University of Leeds)

DESCRIPTION:Hecke categories have been the driving force for understanding
  of how (p-)Kazhdan&ndash\;Lusztig theory controlsrepresentation theory. A
 s one would expect\, singular Hecke categories (should) extend this pictur
 e to moresingular settings (e.g. singular blocks of algebraic groups).\nIn
  this talk we construct an explicit diagrammatic isomorphism between a two
 -colour singular Hecke category and the rational quiver Temperley-Lieb alg
 ebra\, an extension of the usual KLR algebra with &ldquo\;thick strands".
