Higher Groupoids of Gauge Potentials in Higher Gauge Theories admitting Weights

Abstract

We construct an explicit small model for the $\infty$-groupoid of null-concordances of higher gauge curvatures by algorithmically trivializing their nonlinear Bianchi identities. More precisely, for a finite-type Sullivan minimal Bianchi algebra equipped with positive integer weights, we organize weighted potentials and higher gauge parameters at each fixed curvature into an $\infty$-groupoid whose gauge transformations are linear in the parameters. We prove that this model is naturally equivalent to the $\infty$-groupoid of null-concordances through an intermediate total-form model, with explicit projection and section maps and simplicial homotopies. When nonempty, its connected components form a torsor for the degree-zero cohomology of an associated weighted gauge complex, and its higher homotopy groups are computed by the higher cohomology of this complex.
