Stochastic Volterra integral equations with a parameter

open access: yesAdvances in Difference Equations, 2017
In this paper, we study the properties of continuity and differentiability of solutions to stochastic Volterra integral equations and backward stochastic Volterra integral equations depending on a parameter.

Studying Some Stochastic Differential Equations with trigonometric terms with Application

open access: yesZanco Journal of Pure and Applied Sciences, 2022
In this paper we look at several (trigonometric) stochastic differential equations, we find the general form for such nonlinear stochastic differential equation by using the I'to formula.

A boundary integral formalism for stochastic ray tracing in billiards [PDF]

open access: yes, 2014
Determining the flow of rays or non-interacting particles driven by a force or velocity field is fundamental to modelling many physical processes. These include particle flows arising in fluid mechanics and ray flows arising in the geometrical optics ...

On a Neutral Itô and Arbitrary (Fractional) Orders Stochastic Differential Equation with Nonlocal Condition

open access: yesFractal and Fractional, 2021
In this paper, we are concerned with the combinations of the stochastic Itô-differential and the arbitrary (fractional) orders derivatives in a neutral differential equation with a stochastic, nonlinear, nonlocal integral condition.

How to differentiate a quantum stochastic cocycle. [PDF]

open access: yes, 2010
Two new approaches to the infinitesimal characterisation of quantum stochastic cocycles are reviewed. The first concerns mapping cocycles on an operator space and demonstrates the role of H\"older continuity; the second concerns contraction operator ...

Existence and uniqueness of solutions for fractional stochastic delay differential equations

open access: yesXi'an Gongcheng Daxue xuebao, 2021
The existence and uniqueness of solutions for a class fractional stochastic delay differential equations dx(t)=b(x(t), x(t-τ), t)dt+σ1(x(t), x(t-τ), t)dB(t)+σ2(x(t), x(t-τ), t)(dt)α of order α∈(0, 1) were studied.

Stochastic response of fractional-order van der Pol oscillator

open access: yesTheoretical and Applied Mechanics Letters, 2014
We studied the response of fractional-order van de Pol oscillator to Gaussian white noise excitation in this letter. An equivalent integral-order nonlinear stochastic system is obtained to replace the given system based on the principle of minimum mean ...

Asymptotic stochastic characterization of phase and amplitude noise in free-running oscillators [PDF]

open access: yes, 2011
Starting from the definition of the stochastic differential equation for amplitude and phase fluctuations of an oscillator described by an ordinary differential equation, we study the associated Fokker–Planck equation by using tools from stochastic ...
