Starting from an analytic extension of the Feynman-Kac formula and via an appropriate extension of the Cameron-Martin formula, the authors obtain an asymptotic expansion of the solution of Schrödinger’s equation as Planck’s constant tends to zero. The result is contained in Theorem (3.14) where also a probabilistic expression is provided for the different terms of the expansion.
