Solving Partial Integro-Differential Equations via Double Formable Transform

Applied Computational Intelligence and Soft Computing, 2022
In this study, we present a new double integral transform called the double formable transform. Several properties and theorems related to existing conditions, partial derivatives, the double convolution theorem, and others are presented.

Finite element scheme for integro-partial differential equations

, 2008
We construct a finite element like scheme for fully non-linear integro-partial differential equations arising in optimal control of jump-processes. Special cases of these equations include optimal portfolio and option pricing equations in Finance. The schemes are monotone and robust.

On the stability of some stochastic integro partial differential equations

International Journal of Contemporary Mathematical Sciences, 2007
Stochastic integro partial differential equations of the form; du(x, t )= n i=1 ∂ 2 u(x, t) ∂x 2 dt + F (u(x, t) ,x , t)dt + t 0 K(t − θ)u(x, θ)dθdt +[ f (t)u(x, t )+ g(x, t)]dW (t), are considered, where {W (t ): t ≥ 0} is a standard one-dimensional Wiener process and the kernel K decreases to zero non-exponentially.

Exponential Stability of Higher Order Fractional Neutral Stochastic Differential Equation Via Integral Contractors

Mathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6425-6446, April 2025.
ABSTRACT The well‐posedness results for mild solutions to the fractional neutral stochastic differential system with Rosenblatt process with Hurst index Ĥ∈12,1$$ \hat{H}\in \left(\frac{1}{2},1\right) $$ is discussed in this article. To demonstrate the results, the concept of bounded integral contractors is combined with the stochastic result and ...

Finite‐Difference Reduced Transfer Matrix Method for Multibody Systems With Rotating Beams

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Multibody systems with rotating beams serve as critical simplified models of core components in engineering systems; however, existing analytical and numerical methods have limitations in analyzing their complex dynamic behavior. This paper proposes the Finite‐Difference Reduced Multibody System Transfer Matrix Method (FD‐RMSTMM), which ...
