Conservative Continuous-Stage Stochastic Runge–Kutta Methods for Stochastic Differential Equations

open access: yesFractal and Fractional, 2023
In this paper, we develop a new class of conservative continuous-stage stochastic Runge–Kutta methods for solving stochastic differential equations with a conserved quantity. The order conditions of the continuous-stage stochastic Runge–Kutta methods are

Representing a second-order Ito equation as an equation with a given force structure

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2023
The problem of constructing equivalent equations with a given structure of forces by the given system of stochastic equations is considered. The equivalence of equations in the sense of almost surely is investigated.

Stochastic Schrödinger equations [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2004
A derivation of stochastic Schrodinger equations is given using quantum filtering theory. We study an open system in contact with its environment, the electromagnetic field. Continuous observation of the field yields information on the system: it is possible to keep track in real time of the best estimate of the system's quantum state given the ...

Bifurcation of Exact Solutions for the Space-Fractional Stochastic Modified Benjamin–Bona–Mahony Equation

open access: yesFractal and Fractional, 2022
This paper studies the influence of space-fractional and multiplicative noise on the exact solutions of the space-fractional stochastic dispersive modified Benjamin–Bona–Mahony equation, driven in Ito’s sense by a multiplicative Wiener process.

Stochastic Gauss equations [PDF]

open access: yesCelestial Mechanics and Dynamical Astronomy, 2015
We derive the equations of celestial mechanics governing the variations of the orbital elements under a stochastic perturbation generalizing the classical Gauss equations. Explicit formulas are given for the semi-major axis, the eccentricity, the inclination, the longitude of the ascending node, the pericenter angle and the mean anomaly which are ...
