Description
Requiring the absence of gauge and gravitational anomalies places very strong constraints on six-dimensional chiral theories. For 6d supergravity with minimal supersymmetry there is a natural way to identify consistent theories with cliques in a certain multigraph which encodes the pair-wise compatibility of simple, irreducible theories. Leveraging ideas from graph theory, I will discuss the classification of these theories for any number of tensor multiplets and largely unconstrained semi-simple gauge group and hypermultiplet representations.
