The higher category theory can be employed to generalize the BF action to the so-called 3BF action, by passing from the notion of a gauge group to the notion of a gauge three-group. In this work we determine the full gauge symmetry of the 3BF action. To that end, the complete Hamiltonian analysis of the 3BF action for an arbitrary semistrict Lie three-group is performed, by using the Dirac procedure. The Hamiltonian analysis is the first step towards a canonical quantization of a 3BF theory…

Hamiltonian Analysis for the Scalar Electrodynamics as 3BF Theory

TLDR
The complete Hamiltonian analysis of the 3BF action for the choice of a Lie 3-group corresponding to scalar electrodynamics is performed and it is shown that the resulting dynamic constraints eliminate all propagating degrees of freedom.

Higher gauge theories based on 3-groups

A bstractWe study the categorical generalizations of a BF theory to 2BF and 3BF theories, corresponding to 2-groups and 3-groups, in the framework of higher gauge theory. In particular, we construct

An invitation to higher gauge theory

In this easy introduction to higher gauge theory, we describe parallel transport for particles and strings in terms of 2-connections on 2-bundles. Just as ordinary gauge theory involves a gauge

Standard Model and 4-groups

We show that a categorical generalization of the the Poincaré symmetry which is based on the n-crossed modules becomes natural and simple when n = 3 and that the corresponding 3-form and 4-form gauge

Hamiltonian analysis of the BFCG theory for the Poincaré 2-group

We perform the full Hamiltonian analysis of the topological BFCG action based on the Poincaré 2-group. The Hamiltonian of the theory is constructed, and the algebra of constraints is computed. The

Lie crossed modules and gauge-invariant actions for 2-BF theories

We generalize the BF theory action to the case of a general Lie crossed module $(H \to G)$, where $G$ and $H$ are non-abelian Lie groups. Our construction requires the existence of $G$-invariant

We show that general relativity can be formulated as a constrained topological theory for flat 2-connections associated with the Poincaré 2-group. Matter can be consistently coupled to gravity in

Canonical formulation of Poincaré BFCG theory and its quantization

We find the canonical formulation of the Poincaré BFCG theory in terms of the spatial 2-connection and its canonically conjugate momenta. We show that the Poincaré BFCG action is dynamically
