Taking the Liouville theorem as a guiding principle, we propose a possible generalization of classical Hamiltonian dynamics to a three-dimensional phase space. The equation of motion involves two… Expand

It is suggested that the nucleon mass arises largely as a self-energy of some primary fermion field through the same mechanism as the appearance of energy gap in the theory of superconductivity. The… Expand

Relativistic dispersion relations for photomeson production, analogous to the pion-nucleon scattering dispersion relations, are formulated without proof. The assumption that the 33 resonance… Expand

The Weinberg-Salam theory of electromagnetic and weak interactions admits classical configurations in which a pair of magnetic monopoles is bound by a flux string of the Z0 field. They give rise to… Expand

The Nielsen-Olesen interpretation of dual strings as Abrikosov flux lines is extended to the case of open-ended strings by adapting Dirac's description of magnetic monopoles to a London-type theory.… Expand

Ideas and techniques known in quantum electrodynamics have been applied to the Bardeen-Cooper-Schrieffer theoryof superconductivity. In an approximation which corresponds to a generalization of the… Expand

Abstract Infinitisimal variations of the path-dependent phase factor P exp(i∫σAμdzμ) in gauge theory are studied. They are shown to satisfy differential equations which are equivalent to those for a… Expand
