✦ Synopsis
The semiclassical approximation of the coherent-state propagator requires the computation of complex trajectories satisfying special boundary conditions. In this paper we present a method for the determination of such trajectories for one-dimensional polynomial potentials. We also compute the semiclassical propagator for the case V(q)=*q 2 Â2+;q 4 and compare the results with an ``exact'' calculation.
