| Résume | Soergel bimodules categorify Hecke algebras and lead to invariants of
braids that take values in monoidal triangulated categories. In this
process, the quadratic `skein relation' on Artin generators is
promoted to a distinguished triangle. I will talk about an analog of
this relation in the setting of singular Soergel bimodules and Rickard
complexes, in which the distinguished triangle gets replaced by a
longer one-sided twisted complex. Joint work with M. Hogancamp and
D.E.V. Rose. |
