Solvability of a State–Dependence Functional Integro-Differential Inclusion with Delay Nonlocal Condition

open access: yes, 2022
There is great focus on phenomena that depend on their past history or their past state. The mathematical models of these phenomena can be described by differential equations of a self-referred type. This paper is devoted to studying the solvability of a

On the Nonlinear Integro-Differential Equations

open access: yesFractal and Fractional, 2021
The goal of this paper is to study the uniqueness of solutions of several nonlinear Liouville–Caputo integro-differential equations with variable coefficients and initial conditions, as well as an associated coupled system in Banach spaces. The results derived are new and based on Banach’s contractive principle, the multivariate Mittag–Leffler function

Two-dimensional wavelets operational method for solving Volterra weakly singular partial integro-differential equations

open access: yesJournal of Computational and Applied Mathematics, 2020
In this article, we discuss a method for finding an approximate solution of a class of two-dimensional linear Volterra weakly partial integro-differential equations.

Random Carbon Tax Policy and Investment Into Emission Abatement Technologies

open access: yesMathematical Finance, EarlyView.
ABSTRACT We analyze the problem of a profit‐maximizing electricity producer, subject to carbon taxes, who decides on investments into CO2$\rm CO_2$ abatement technologies. We assume that the carbon tax policy is random and that the investment in the abatement technology is divisible, irreversible, and subject to transaction costs.

Stochastic partial differential and integro-differential equations [PDF]

open access: yes, 2015
In this work we present some new results concerning stochastic partial differential and integro-differential equations (SPDEs and SPIDEs) that appear in non-linear filtering.

The spread of non‐native species

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1197-1234, June 2026.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

On a Simple Type of Integro-differential Equation [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 1935
In a previous paper in these Proceedings the author discussed conditions for a maximum or minimum of functions of integrals of the typeusing the methods of the Calculus of Variations. In the effort to establish a third necessary condition for a minimum—the analogue of Jacobi's condition in the ordinary variational problem—it was found that the analogue

Numerical Modeling of Inertial Particles in Three‐Dimensional Fluid Flow

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT The motion of inertial particles in a fluid is modeled by the Maxey–Riley–Gatignol equation (MaRGE). The MaRGE contains an integral term that arises due to the viscous diffusion of vorticity in the fluid around the particle. Because it makes MaRGE difficult to solve numerically, the integral term is often neglected or approximated, despite its

On high order fractional integro-differential equations including the Caputo–Fabrizio derivative

open access: yesBoundary Value Problems, 2018
By using the fractional Caputo–Fabrizio derivative, we introduce two types new high order derivations called CFD and DCF. Also, we study the existence of solutions for two such type high order fractional integro-differential equations.

On the behavior of the solutions for certain neutral delay integro-differential equations [PDF]

open access: yesE-Journal of Analysis and Applied Mathematics
Some results are given on the behavior of solutions of scalar linear and constant coefficient neutral delay integro-differential equations. These results are obtained using two different real roots of the relevant characteristic equation.
