Abstract

Feynman integral is defined for operator-valued maps which are Fourier transforms of an operator-valued measure of bounded variation. Such an integral is then used to describe perturbation of certain unitary groups by certain cocycles.

Feynman path integral of Riemann type

Kiyoko Furuya

In this paper, we shall define a kind of operator-valued integration and define the Feynman path integrals of Riemann integral type. It seems that it is one of the best possible conditions of the existence of the path integrals of Riemann integral type for the Schrödinger equation with singular potentials. Our class of potentials is wide enough: the real measurable potential U should be continuous except for a closed set of measure zero.

Integral transform as operator-valued Feynman integrals via conditional Feynman integrals over Wiener paths in abstract Wiener space

Dong Hyun Cho

In this article, we introduce an integral transform as operator-valued Feynman integrals over Wiener paths in abstract Wiener space. In addition, we evaluate the integral transform for various types of functions, which are of interest in quantum mechanics and Feynman integration theories, via the conditional Feynman integral over Wiener paths in abstract Wiener space as a kernel.

Star-product representation of path integrals

Pankaj Sharan

It is shown that Feynman's path integral can be written as a Fourier transform of a function defined on the classical phase space with the help of the star product recently introduced by Bayen, Flato, Fronsdal, Lichnerowicz, and Sternheimer. This gives a well-defined meaning to path integrals and may prove to be a useful tool in their actual evaluation.

Transformations of path integrals

Kumar S Narain, Jan Tarski

Several examples of changes of variables in Feynman-type integrals are considered. In particular, path integrals in curvilinear coordinates (of a certain class) are rigorously defined. An appendix is devoted to path integrals for vector potentials.

The Feynman integral as a limit of complex measures

José L. Martínez-Morales

The fundamental solution of the Schrödinger equation for a free particle is a distribution. This distribution can be approximated by a sequence of smooth functions. It is defined for each one of these functions, a complex measure on the space of paths. For certain test functions, the limit of the integrals of a test function with respect to the complex measures, exists. We define the Feynman integral of one such function by this limit.

Feynman Path Integral Using Operator Integration in Banach Space

Reza Ahangar, Erbil Çetin, Şerife Müge Ege

Feynman-Path Integral in Banach Space: In 1940, R.P. Feynman attempted to find a mathematical representation to express quantum dynamics of the general form for a double-slit experiment. His intuition on several slits with several walls in terms of Lagrangian instead of Hamiltonian resulted in a magnificent work. It was known as Feynman Path Integrals in quantum physics, and a large part of the scientific community still considers them a heuristic tool that lacks a sound mathematical definition. This paper aims to refute this prejudice, by providing an extensive and self-contained description of the mathematical theory of Feynman Path Integration, from the earlier attempts to the latest developments, as well as its applications to quantum mechanics. About a hundred years after the beginning of modern physics, it was realized that light could in fact show behavioral characteristics of both waves and particles. In 1927, Davisson and Germer demonstrated that electrons show the same dual behavior, which was later extended to atoms and molecules. We shall follow the method of integration with some modifications to construct a generalized Lebesgue-Bochner-Stieltjes (LBS) integral of the form , where u is a bilinear operator acting in the product of Banach spaces, f is a Bochner summable function, and μ is a vector-valued measure. We will demonstrate that the Feynman Path Integral is consistent and can be justified mathematically with LBS integration approach.
