Web8. feb 2024 · An approach to the categorification of a perverse sheaf on a disc was suggested in [Reference Kapranov and Schechtman KS14]. The datum of a perverse sheaf on a disc with a single singularity in the centre is equivalent to the datum of a certain quiver diagram; the proposed ad hoc categorification of the quiver description is a spherical … WebAbstractIn this article we consider the general deﬁnition of Lusztig sheaves for arbitrary quivers, possibly carrying loops.
