The probabilistic approach to the analysis of the limiting behavior of an integro‐diffebential equation depending on a small parameter, and its application to stochastic processes

open access: yesInternational Journal of Stochastic Analysis, Volume 7, Issue 1, Page 25-31, 1994., 1994
Using connection between stochastic differential equation with Poisson measure term and its Kolmogorov′s equation, we investigate the limiting behavior of the Cauchy problem solution of the integro differential equation with coefficients depending on a small parameter. We also study the dependence of the limiting equation on the order of the parameter.

Pseudo S-asymptotically Bloch type periodicity with applications to partial stochastic neutral evolution equations [PDF]

open access: yesArab Journal of Mathematical Sciences
PurposeThis paper introduces the concept of (µ, ν)-pseudo S-asymptotically Bloch type (ω, k)- periodic functions, aiming to extend the framework of periodicity in stochastic analysis and to investigate their role in neutral partial stochastic ...

Generalized functionals of Brownian motion

open access: yesInternational Journal of Stochastic Analysis, Volume 7, Issue 3, Page 247-267, 1994., 1993
In this paper we discuss some recent developments in the theory of generalized functionals of Brownian motion. First we give a brief summary of the Wiener‐Ito multiple Integrals. We discuss some of their basic properties, and related functional analysis on Wiener measure space. then we discuss the generalized functionals constructed by Hida.

A Perturbation Theory for Ergodic Properties of Markov Chains [PDF]

open access: yes, 2000
Perturbations to Markov chains and Markov processes are considered. The unperturbed problem is assumed to be geometrically ergodic in the sense usually established through use of Foster-Lyapunov drift conditions.

On the Cauchy problem of a degenerate parabolic-hyperbolic PDE with Lévy noise

open access: yesAdvances in Nonlinear Analysis, 2017
In this article, we deal with the stochastic perturbation of degenerate parabolic partial differential equations (PDEs). The particular emphasis is on analyzing the effects of a multiplicative Lévy noise on such problems and on establishing a well ...

Stochastic stability and instability of rumor model

open access: yesOpen Mathematics
In this study, we present a stochastic rumor model. The stability of the disease-free equilibrium state and instability of the free equilibrium E0{E}_{0} of stochastic epidemics model are considered with the help of Lyapunov functions.

Probability structure preserving and absolute continuity [PDF]

open access: yes, 2002
. – The concept of probability structure preserving mapping is introduced. The idea is applied to define stochastic integral for fractional Brownian motion (fBm) and to obtain an anticipative Girsanov theorem for fBm.

Sub- and Super-solutions of a Nonlinear PDE, and Application to a Semilinear SPDE [PDF]

open access: yes, 2013
2010 Mathematics Subject Classification: 35R60, 60H15, 74H35.We obtain upper and lower bounds for the explosion time of a semi-linear heat equation on a bounded $d$-dimensional domain, perturbed by white noise. The bounds we get are expressed in terms of

Early warning signs for SPDEs with continuous spectrum

open access: yesEuropean Journal of Applied Mathematics
In this work, we study early warning signs for stochastic partial differential equations (SPDEs), where the linearisation around a steady state is characterised by continuous spectrum. The studied warning sign takes the form of qualitative changes in the
