Path Integrals and Product Integrals
Journal of Mathematical Physics, 1971The product integral is shown to be the appropriate mathematical tool for implementing the path integral for spin in its simplest form.

Feynman started the theory of quantum computation by observing that quantum mechanical amplitudes cannot be simulated efficiently on a computer, since path integrals are computationally hard. Path integrals are heuristic tools for Schrödinger's hamiltonians, at least for real time dynamics. On the contrary they have a rigorous mathematical meaning for

The matrix elements between wavelets of the quantum propagator for a large class of Hamiltonians on the half-line are given in terms of path integral. It is a sum over path defined on the upper half plane with a Wiener measure associated to the hyperbolic Laplacian in the limit where the diffusion constant diverges.

The goal of this chapter is to develop Wiener's path integral formulation of stochastic processes, with particular emphasis on its application to nonequilibrium thermodynamics. After deriving the path integral for the propagator of a free Brownian particle, its extension to a particle in a force field is determined.

Abstract An elegant alternative formalism of quantum mechanics was given by R. P. Feynman in 1948. The importance of this formalism, known as the path integral, functional integral, etc. approach, first of all lies in its vivid, intuitive description of quantum fluctuations.
