Large deviations for stochastic Kuramoto–Sivashinsky equation with multiplicative noise

open access: yesNonlinear Analysis, 2021
The Kuramoto–Sivashinsky equation is a nonlinear parabolic partial differential equation, which describes the instability and turbulence of waves in chemical reactions and laminar flames. The aim of this work is to prove the large deviation principle for

Nash Equilibrium of Stochastic Partial Differential Game with Partial Information via Malliavin Calculus

open access: yesComplexity, 2023
In this article, we consider the Nash equilibrium of stochastic differential game where the state process is governed by a controlled stochastic partial differential equation and the information available to the controllers is possibly less than the ...

Using Nonlinear Diffusion Model to Identify Music Signals

open access: yesAdvances in Mathematical Physics, 2021
In this paper, combined with the partial differential equation music signal smoothing model, a new music signal recognition model is proposed. Experimental results show that this model has the advantages of the above two models at the same time, which ...

A direct approach to linear-quadratic stochastic control [PDF]

open access: yesOpuscula Mathematica, 2017
A direct approach is used to solve some linear-quadratic stochastic control problems for Brownian motion and other noise processes. This direct method does not require solving Hamilton-Jacobi-Bellman partial differential equations or backward stochastic ...

Probabilistic Representations of Solutions of the Forward Equations [PDF]

open access: yes, 2007
In this paper we prove a stochastic representation for solutions of the evolution equation $ \partial_t \psi_t = {1/2}L^*\psi_t $ where $ L^* $ is the formal adjoint of an elliptic second order differential operator with smooth coefficients corresponding

A Proposed Stochastic Finite Difference Approach Based on Homogenous Chaos Expansion

open access: yesJournal of Applied Mathematics, 2013
This paper proposes a stochastic finite difference approach, based on homogenous chaos expansion (SFDHC). The said approach can handle time dependent nonlinear as well as linear systems with deterministic or stochastic initial and boundary conditions. In

On the series solution of the stochastic Newell Whitehead Segel equation

open access: yesAIMS Mathematics, 2023
The purpose of this paper is to present a two-step approach for finding the series solution of the stochastic Newell-Whitehead-Segel (NWS) equation. The proposed two-step approach starts with the use of the Wiener-Hermite expansion (WHE) technique, which

Linearly Solvable Stochastic Control Lyapunov Functions [PDF]

open access: yes, 2016
This paper presents a new method for synthesizing stochastic control Lyapunov functions for a class of nonlinear stochastic control systems. The technique relies on a transformation of the classical nonlinear Hamilton-Jacobi-Bellman partial differential ...
