Existence for stochastic sweeping process with fractional Brownian motion [PDF]

open access: yes, 2022
This paper is devoted to the study of a convex stochastic sweeping process with fractional Brownian by time delay. The approach is based on discretizing stochastic functional differential inclusions.

Existence and topological structure of solution sets for φ-Laplacian impulsive stochastic differential systems [PDF]

open access: yes, 2018
In this article, we present results on the existence and the topological structure of the solution set for initial-value problems relating to the first-order impulsive differential equation with infinite Brownian motions are proved. The approach is based

A family of integral representations for the brownian variables [PDF]

open access: yes, 2003
. – The natural filtration of a real Brownian motion and its excursion filtration are sharing a fundamental property: the property of integral representation. As a consequence, every Brownian variable admits two distinct integral representations. We show

An extension of the stochastic sewing lemma and applications to fractional stochastic calculus

open access: yesForum of Mathematics, Sigma
We give an extension of Lê’s stochastic sewing lemma. The stochastic sewing lemma proves convergence in $L_m$ of Riemann type sums $\sum _{[s,t] \in \pi } A_{s,t}$ for an adapted two-parameter stochastic process A, under certain conditions ...

Behavior with respect to the Hurst index of the Wiener Hermite integrals and application to SPDEs

open access: yes, 2019
International audienceWe consider the Wiener integral with respect to a d-parameter Hermite process with Hurst multi-index H = (H 1 , .., H d) ∈ 1 2 , 1 d and we analyze the limit behavior in distribution of this object when the components of H tend to 1

Multiple G-Stratonovich integral in G-expectation space

open access: yesOpen Mathematics
The Stratonovich integral represents a fundamental concept in stochastic calculus. In this article, we first propose a novel approach inspired by the multidimensional G-Itô formula, establishing a multiple G-Stratonovich integral within the G-expectation

On the weak convergence of multiparameter stochastic integrals

open access: yesOpen Mathematics
In this paper we provide sufficient conditions for sequences of stochastic processes of the form ∫ [0,t] f n(u)θ n(u)du, to weakly converge, in the space of continuous functions over a closed interval, to integrals with respect to the Brownian motion, ∫ [

Probability structure preserving and absolute continuity [PDF]

open access: yes, 2002
. – The concept of probability structure preserving mapping is introduced. The idea is applied to define stochastic integral for fractional Brownian motion (fBm) and to obtain an anticipative Girsanov theorem for fBm.

Multiple stochastic integral expansions of arbitrary Poisson jump times functionals

open access: yes, 1999
We compute the Wiener-Poisson expansion of square-integrable functionals of a finite number of Poisson jump times in series of multiple Poisson stochastic integrals. Key words: Fock space, Poisson process, Wiener chaos.
