A Uniform Approximation for the Coherent State Propagator using a   Conjugate Application of the Bargmann Representation
  We propose a conjugate application of the Bargmann representation of quantum mechanics. Applying the Maslov method to the semiclassical connection formula between the two representations, we derive a uniform semiclassical approximation for the coherent state propagator which is finite at phase space caustics.
