On étudie une équation de Schrödinger avec une dépendence temporelle dans un potentiel quadratique ainsi que dans un potentiel quartique. L'existence de solutions est démontrée ainsi qu'une représentation en termes d'integrales de chemins de Feynman, définis rigoureusement comme intégrales oscillatoires en dimension infinie.
The Schrödinger equation with a time dependence in both a quadratic and a quartic potential is considered. Existence of solutions is shown and a rigorous Feynman path integral representation for the solution is given in terms of well-defined infinite-dimensional oscillatory integrals.
