State Path

A wide class of single-variable holomorphic representation spaces are constructed that are associated with very general sets of coherent states defined without the use of transitively acting groups. These representations and states are used to define coherent-state path integrals involving phase-space manifolds having one Killing vector but a quite general curvature otherwise.

State Path

After reviewing coherent state path integrals for nonrelativistic spin in four dimensions (or equivalently, relativistic spin in three dimensions), the Dirac propagator in four dimensions is recast as a functional integral of an (S3×S3)/S1 field. Chiral transformations correspond to a global rotation of this field.
