    The category-theoretic formulation of twisted intertwiners

    (for the latter I am citing Fuchs, Schweigert et al. 2000, but the notion will be older and there may be older terminology for it, let me know if you have a reference )

    more formulas and more diagrams

    (on the higher morphisms between twisted intertwiners – have never seen these discussed in the literature, have they been?)

    made explicit in components (here) how “deformation” of twisted intertwiners is an equivalence relation respected by composition (hence giving a component-description of the homotopy category of the 2-category of representations, twisted intertwiners and their deformations).
