We prove that the Wiener integral, the analytic Wiener integral and the analytic Feynman integral of the first variation of F(x)=exp{∫0Tθ(t,x(t))dt} successfully exist under the certain condition, where θ(t,u)=∫Rexp{iuv}dσt(v) is a Fourier–Stieltjes ...

A change of scale formula for Wiener integrals of cylinder functions on abstract Wiener space
The purpose of this paper is to establish the existence of analytic Wiener and Feynman integrals for a class of certain cylinder functions which is of the form: F(x)=f((h1,x)∼,⋯,(hn,x)∼), x∈B, on the abstract Wiener space, and to establish the ...

A Partial Derivative Approach to the Change of Scale Formula for the Function Space Integral
We investigate the partial derivative approach to the change of scale formula for the functon space integral and we investigate the vector calculus approach to the directional derivative on the function space and prove relationships among the Wiener ...

A change of scale formula for Wiener integrals on abstract Wiener spaces
In this paper we obtain a change of scale formula for Wiener integrals on abstract Wiener spaces. This formula is shown to hold for many classes of functions of interest in Feynman integration theory and quantum mechanics.

Wiener Functionals as Itô Integrals [PDF]
Let W(t, ω) be a standard Wiener process, W t ≡ W(t) ≡ W(t, ∙). A function φ(t, ω) is called nonanticipating iff for all t ^ 0, φ(t, ∙) is measurable with respect to {W s : 0 % s % t}. The Ito stochastic integral $$f(\omega )\, \equiv \,\int {_0^1 \varphi (t,\,\omega )d_t \,W(t,\,\omega )}$$ is defined for any jointly measurable, nonanticipating ...

Fundamental theorem of Wiener calculus
In this paper we define and develop a theory of differentiation in Wiener space C[0,T]. We then proceed to establish a fundamental theorem of the integral calculus for C[0,T].

An Operator-Valued Yeh-Wiener Integral and a Kac-Feynman Wiener Integral Equation [PDF]
Let C [ 0 , T ] C[0,T] denote Wiener space, i.e., the space of all continuous functions η ( t ) \eta (t) on [ 0 , T ] [0,T] such that η ( 0 ) = 0

Using simple formulas for generalized conditional Wiener integrals on a function space which is an analogue of Wiener space, we evaluate two generalized analytic conditional Wiener integrals of a generalized cylinder function which is useful in Feynman ...

On Determinant Expansions for Hankel Operators
Let w be a semiclassical weight that is generic in Magnus’s sense, and (pn)n=0∞({p_n})_{n = 0}^\infty the corresponding sequence of orthogonal polynomials. We express the Christoffel–Darboux kernel as a sum of products of Hankel integral operators.
