Abstract: Sheaves on moment graphs have become a powerful tool in representation theory thanks to the work of Fiebig, Shan, Varagnolo, Vasserot and Williamson. In this talk we will associate to any singular Bruhat graph a certain category of sheaves on it and show that it categorifies the corresponding parabolic Hecke module.
