An Extension of the Stochastic Integral

open access: yesThe Annals of Probability, 1982
Two related extensions of the stochastic integral are discussed. These extensions allow the integrand to anticipate the Brownian motion, and arise in the study of linear stochastic integral equations. The development is based on the homogeneous chaos expansion of the integrand.

On extended stochastic integrals with respect to Lévy processes

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2013
Let $L$ be a Levy process on $[0,+\infty)$. In particular cases, when $L$ is a Wiener or Poisson process, any square integrable random variable can be decomposed in a series of repeated stochastic integrals from nonrandom functions with respect to $L ...

The Implementation of Milstein Scheme in Two-Dimensional SDEs Using the Fourier Method

open access: yesAbstract and Applied Analysis, 2018
Multiple stochastic integrals of higher multiplicity cannot always be expressed in terms of simpler stochastic integrals, especially when the Wiener process is multidimensional. In this paper we describe how the Fourier series expansion of Wiener process

Stochastic Lie Group Integrators [PDF]

open access: yesSIAM Journal on Scientific Computing, 2008
We present Lie group integrators for nonlinear stochastic differential equations with non-commutative vector fields whose solution evolves on a smooth finite dimensional manifold. Given a Lie group action that generates transport along the manifold, we pull back the stochastic flow on the manifold to the Lie group via the action, and subsequently pull ...

Quantum stochastic integrals as operators [PDF]

open access: yes, 2010
We construct quantum stochastic integrals for the integrator being a martingale in a von Neumann algebra, and the integrand -- a suitable process with values in the same algebra, as densely defined operators affiliated with the algebra.

Explicit order 3/2 Runge-Kutta method for numerical solutions of stochastic differential equations by using Itô-Taylor expansion

open access: yesOpen Mathematics, 2019
This paper aims to present a new pathwise approximation method, which gives approximate solutions of order 32$\begin{array}{} \displaystyle \frac{3}{2} \end{array}$ for stochastic differential equations (SDEs) driven by multidimensional Brownian motions.

A note on Kurzweil-Henstock's anticipating non-stochastic integral [PDF]

open access: yesMathematica Bohemica
Motivated by the study of anticipating stochastic integrals using Kurzweil-Henstock approach, we use anticipating interval-point pairs (with the tag as the right-end point of the interval) in studying non-stochastic integral, which we call the Kurzweil ...

Functionals in stochastic thermodynamics: how to interpret stochastic integrals [PDF]

open access: yes, 2019
In stochastic thermodynamics standard concepts from macroscopic thermodynamics, such as heat, work, and entropy production, are generalized to small fluctuating systems by defining them on a trajectory-wise level.

Optimal Portfolios for Different Anticipating Integrals under Insider Information

open access: yesMathematics, 2020
We consider the non-adapted version of a simple problem of portfolio optimization in a financial market that results from the presence of insider information. We analyze it via anticipating stochastic calculus and compare the results obtained by means of
