Abstract

This is the second of a series of four articles studying various generalisations of Khovanov’s diagram algebra. In this article we develop the general theory of Khovanov’s diagrammatically defined “projective functors” in our setting. As an application, we give a direct proof of the fact that the quasi-hereditary covers of generalised Khovanov algebras are… (More)
