We study the Dirac equation with slowly varying external potentials. Using matrix-valued Wigner functions we prove that the electron follows with high precision the classical orbit and that the spin precesses according to the BMT equation with gyromagnetic ratio g=2. 2000

It is shown how by combining the ideas of the direct perturbation theory approach to the solution of the Dirac equation and the regular expansion as used in the Chang-PClissier-Durand Hamiltonian one can derive a spin-free approximation to the Dirac equation that resembles a similar equation recent

We construct a new kind of path integral for the Dirac equation propagator, intended as an extension to 3 space dimensions of the Feynman ``checkerboard'' propagator. One form of this path integral is a ``projector path'' summation, out of which one can reconstruct standard 3D space and chirality. O
