Outline of Final Research Achievements |
We gave a general class of functionals for which the phase space path integrals of higher order parabolic type have a mathematically rigorous meaning. For any functional belonging to this class, the time slicing approximation of the phase space path integral, converges uniformly on compact subsets with respect to the endpoint of position paths and to the starting point of momentum paths. Because this class of functionals is closed under addition and multiplication, we can produce many functionals which are path integrable. Furthermore, though we need to pay attention for use, the interchange of the order of the phase space path integrals and some integrals, and the interchange of the order of the phase space path integrals and some limit operations, are valid.
