This, besides agreeing with the classical electron radius as well as with the canonical momentum
of a charged particle in an external field, in the sense that P = e[A.
The final chapters discuss the exploitation of the canonical conservation law of momentum in nonlinear wave propagation, the application of canonical momentum
conservation law and material force in numerical schemes, and similarities of fluid mechanics and aerodynamics.
A Lagrangian is associated with the particle from which the canonical momentum is derived.
With reference to this Lagrangian, the canonical momentum associated with this particle is
where canonical momentum
in a gravitational field is p = [m.
