Pyramids and 2-representations

Representation Theory 2017-05-10 v1

Abstract

We describe a diagrammatic procedure which lifts strict monoidal actions from additive categories to categories of complexes avoiding any use of direct sums. As an application, we prove that every simple transitive 22-representation of the 22-category of projective bimodules over a finite dimensional algebra is equivalent to a cell 22-representation.
