Abstract: (Elsevier)
Quantum chromodynamics is investigated in the axial gauge with particular attention to boundary terms. The Poincaré algebra has anomalies and closes only in the gauge-invariant physical sector. A simple method is proposed for dealing with the boundary condition E 3 a → 0 as x 3 → ∞ in a Hamiltonian formalism. It is found that the gauge potentials have physically meaningful non-trivial asymptotic behavior related to instanton effects. This presents an obstacle to perturbation theory.- QUANTUM CHROMODYNAMICS: FOUR-DIMENSIONAL
