On the Reduction of Integro-Differential Equations [PDF]

open access: yesTransactions of the American Mathematical Society, 1914
which is satisfied by the potential V of an electric field in an isotropic medium, in the so-called " static case " of hysteresis.t By solving this equation, regarded as an integral equation, for V2V, we are led to the differential equation of Poisson to determine V.

On the existence of solutions for a pointwise defined multi-singular integro-differential equation with integral boundary condition

open access: yes, 2020
It is important that we increase our ability for studying of complicate fractional integro-differential equation. In this paper, we investigates the existence of solutions for a pointwise defined multi-singular fractional differential equation under some

Stability of the spline collocation method for second order Volterra integro‐differential equations

open access: yesMathematical Modelling and Analysis, 2004
Numerical stability of the spline collocation method for the 2nd order Volterra integro‐differential equation is investigated and connection between this theory and corresponding theory for the 1st order Volterra integro‐differential equation is ...

Existence and uniqueness of a solution to a partial integro-differential equation by the method of lines

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2008
In this work we consider a partial integro-differential equation. We reformulate it a functional integro-differential equation in a suitable Hilbert space. We apply the method of lines to establish the existence and uniqueness of a strong solution.

An inverse problem for a nonlinear Fredholm integro-differential equation of fourth order with degenerate kernel

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015
We consider the questions of one value solvability of the inverse problem for a nonlinear partial Fredholm type integro-differential equation of the fourth order with degenerate kernel. The method of degenerate kernel is developed for the case of inverse

On $$L_p$$-solvability of stochastic integro-differential equations [PDF]

open access: yesStochastics and Partial Differential Equations: Analysis and Computations, 2020
AbstractA class of (possibly) degenerate stochastic integro-differential equations of parabolic type is considered, which includes the Zakai equation in nonlinear filtering for jump diffusions. Existence and uniqueness of the solutions are established in Bessel potential spaces.

Variational Iteration Method for Solving Fractional Integro-Differential Equations with Conformable Differointegration

open access: yesAxioms, 2022
Multidimensional integro-differential equations are obtained when the unknown function of several independent variable and/or its derivatives appear under an integral sign. When the differentiation or integration operators or both are of fractional order,

Accelerating Solutions in Integro-Differential Equations [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2011
In this paper, we study the spreading properties of the solutions of an integro-differential equation of the form $u_t=J\ast u-u+f(u).$ We focus on equations with slowly decaying dispersal kernels $J(x)$ which correspond to models of population dynamics with long-distance dispersal events. We prove that for kernels $J$ which decrease to $0$ slower than
