DESCRIPTION:Hecke categories have been the driving force for understanding
  of how (p-)Kazhdan–Lusztig theory controls representation theory. As on
 e would expect\, singular Hecke categories (should) extend this picture to
  more singular settings (e.g. singular blocks of algebraic groups). In thi
 s talk we construct an explicit diagrammatic isomorphism between a two-col
 our singular Hecke category and the rational quiver Temperley-Lieb algebra
 \, an extension of the usual KLR algebra with “thick strands". This is b
 ased on joint work with Chris Bowman\, Maud De Visscher\, and Catharina St
 roppel.
