A Delayed Black and Scholes Formula I [PDF]
, 2006 In this article we develop an explicit formula for pricing European options when the underlying stock price follows a non-linear stochastic differential delay equation (sdde). We believe that the proposed model is sufficiently flexible to fit real market

A linear numerical scheme for nonlinear BSDEs with uniformly continuous coefficients
Journal of Applied Mathematics, Volume 2004, Issue 6, Page 461-477, 2004., 2004 We attempt to present a new numerical approach to solve nonlinear backward stochastic differential equations. First, we present some definitions and theorems to obtain the condition, from which we can approximate the nonlinear term of the backward stochastic differential equation (BSDE) and we get a continuous piecewise linear BSDE corresponding to the

Stochastic flows with interaction and measure‐valued processes
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 63, Page 3963-3977, 2003., 2003 We consider the new class of the Markov measure‐valued stochastic processes with constant mass. We give the construction of such processes with the family of the probabilities which describe the motion of single particles. We also consider examples related to stochastic flows with the interactions and the local times for such processes.

Intermittent quasistatic dynamical systems: weak convergence of fluctuations
Nonautonomous Dynamical Systems, 2018 This paper is about statistical properties of quasistatic dynamical systems. These are a class of non-stationary systems that model situations where the dynamics change very slowly over time due to external influences. We focus on the case where the time-

Functional integro‐differential stochastic evolution equations in Hilbert space
International Journal of Stochastic Analysis, Volume 16, Issue 2, Page 141-161, 2003., 2003 We investigate a class of abstract functional integro‐differential stochastic evolution equations in a real separable Hilbert space. Global existence results concerning mild and periodic solutions are formulated under various growth and compactness conditions.

Dynamical behavior for a stochastic two-species competitive model
Open Mathematics, 2017 This paper deals with a stochastic two-species competitive model. Some very verifiable criteria on the global stability of the positive equilibrium of the deterministic system are established.

Periodicity in distribution. I. Discrete systems
International Journal of Mathematics and Mathematical Sciences, Volume 30, Issue 2, Page 65-127, 2002., 2002 We consider the existence of periodic in distribution solutions to the difference equations in a Banach space. A random process is called periodic in distribution if all its finite‐dimensional distributions are periodic with respect to shift of time with one period. Only averaged characteristics of a periodic process are periodic functions.

Approximations of center manifolds for delay stochastic differential equations with additive noise
Advances in Nonlinear Analysis, 2023 This article deals with approximations of center manifolds for delay stochastic differential equations with additive noise. We first prove the existence and smoothness of random center manifolds for these approximation equations. Then we show that the Ck{

The arctangent law for a certain random time related to a one-dimensional diffusion
, 2017 For a time-homogeneous, one-dimensional diffusion process $X(t),$ we investigate the distribution of the first instant, after a given time $r,$ at which $X(t)$ exceeds its maximum on the interval $[0,r],$ generalizing a result of Papanicolaou, which is ...

Discretizing a backward stochastic differential equation
International Journal of Mathematics and Mathematical Sciences, Volume 32, Issue 2, Page 103-116, 2002., 2002 We show a simple method to discretize Pardoux‐Peng′s nonlinear backward stochastic differential equation. This discretization scheme also gives a numerical method to solve a class of semi‐linear PDEs.
