Feynman integral and complex classical trajectories

Let _t be an analytic solution of the Schrödinger equation with the initial condition . Let _t be the solution of the Schrödinger equation with the initial condition =, where is an analytic function. When 0, then _t(x)_t(x)¹ (_t(x)), where _t(x) trajectory starting from x. We relate this result to Feynman's sum over trajectories and complex stochastic differential equations.
