Non-Abelian Combinatorial Gauge Theory

Abstract

Building on the principle of combinatorial gauge symmetry, lattice gauge theories can be formulated with only one- and two-body interactions that ensure the exact realization of the symmetry rather than its approximate emergence in a perturbative regime. This paper extends the framework to encompass generic non-Abelian finite gauge groups by expanding on previous work that developed the theory for finite Abelian gauge groups and presented one non-Abelian example.
