Anticipative backward stochastic differential equations driven by fractional Brownian motion

open access: yes, 2016
We study the anticipative backward stochastic differential equations (BSDEs, for short) driven by fractional Brownian motion with Hurst parameter H greater than 1/2.

On the probabilistic solution of the Cauchy problem for parabolic equations

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2017
The questions about finding (conditional) mathematical expectations, the joint and marginal distribution of different functionals from the trajectories of random processes, expressed through the process itself, the ordinary stochastic integral and the ...

A Differentiation Theory for It\^o's Calculus

open access: yes, 2010
A peculiar feature of It\^o's calculus is that it is an integral calculus that gives no explicit derivative with a systematic differentiation theory counterpart, as in elementary calculus.

On maximal inequalities for purely discontinuous martingales in infinite dimensions

open access: yes, 2013
The purpose of this paper is to give a survey of a class of maximal inequalities for purely discontinuous martingales, as well as for stochastic integral and convolutions with respect to Poisson measures, in infinite dimensional spaces.

On the existence and uniqueness of solutions to stochastic differential equations driven by G-Brownian motion with integral-Lipschitz coefficients

open access: yes, 2014
In this paper, we study the existence and uniqueness of solutions to stochastic differential equations driven by G-Brownian motion (GSDEs) with integral-Lipschitz conditions on their ...

Fractional L\'{e}vy-driven Ornstein--Uhlenbeck processes and stochastic differential equations

open access: yes, 2011
Using Riemann-Stieltjes methods for integrators of bounded $p$-variation we define a pathwise integral driven by a fractional L\'{e}vy process (FLP). To explicitly solve general fractional stochastic differential equations (SDEs) we introduce an Ornstein-

The Stochastic Quantization Method in Phase Space and a New Gauge Fixing Procedure

open access: yes, 1993
We study the stochastic quantization of the system with first class constraints in phase space. Though the Langevin equations of the canonical variables are defined without ordinary gauge fixing procedure, gauge fixing conditions are automatically ...

On the Construction of Some Fractional Stochastic Gompertz Models

open access: yesMathematics, 2020
The aim of this paper is the construction of stochastic versions for some fractional Gompertz curves. To do this, we first study a class of linear fractional-integral stochastic equations, proving existence and uniqueness of a Gaussian solution.
