Towards a theory of functions in abstract Wiener spaces

open access: greenPhysica D: Nonlinear Phenomena, 2009
The basic results on the theory of functions of bounded variation in an abstract Wiener space are discussed. First of all, the tools of the corresponding finite dimensional theory are carefully examined in order to find those results which are still helpful in infinite dimensional setting.

A Note on Function Spaces with Fractional Fourier Transforms in Wiener-type Spaces

open access: yesDüzce Üniversitesi Bilim ve Teknoloji Dergisi, 2023
The purpose of this paper is to introduce and study a function space A_(α,w)^(B,Y) (R^d ) to be a linear space of functions h∈L_w^1 (R^d ) whose fractional Fourier transforms F_α h belong to the Wiener-type space W(B,Y)(R^d ), where w is a Beurling ...

A Modified Generalized Analytic Feynman Integral Associated with the Bounded Linear Operator

open access: yesAxioms, 2022
In this paper, we define a modified and generalized analytic Feynman integral associated with the bounded linear operator on abstract Wiener spaces. We then prove its existence. We also establish some modified and generalized analytic Feynman integration

Asymptotic pointwise error estimates for reconstructing shift-invariant signals with generators in a hybrid-norm space

open access: yesJournal of Inequalities and Applications, 2021
Sampling and reconstruction of signals in a shift-invariant space are generally studied under the requirement that the generator is in a stronger Wiener amalgam space, and the error estimates are usually given in the sense of L p , 1 / ω $L_{p,{1 ...

Some remarks about the positivity of random variables on a Gaussian probability space [PDF]

open access: yes, 2004
Let $(W,H,\mu)$ be an abstract Wiener space and $L$ be a probability density of class LlogL. Using the measure transportation of Monge-Kantorovitch, we prove that the kernel of the projection of L on the second Wiener chaos defines an (Hilbert-Schmidt ...

The Monge problem in Wiener Space [PDF]

open access: yes, 2011
We address the Monge problem in the abstract Wiener space and we give an existence result provided both marginal measures are absolutely continuous with respect to the infinite dimensional Gaussian measure {\gamma}

A fractional Brownian field indexed by $L^2$ and a varying Hurst parameter [PDF]

open access: yes, 2014
Using structures of Abstract Wiener Spaces, we define a fractional Brownian field indexed by a product space $(0,1/2] \times L^2(T,m)$, $(T,m)$ a separable measure space, where the first coordinate corresponds to the Hurst parameter of fractional ...
