Extensions of some differential inequalities for fractional integro-differential equations via upper and lower solutions [PDF]

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2023
This paper deals with some differential inequalities for generalized fractional integro-differential equations by using the technique of upper and lower solutions. The fractional differential operator is taken in Caputo’s sense and the nonlinear

A Symbolic Method for Solving a Class of Convolution-Type Volterra–Fredholm–Hammerstein Integro-Differential Equations under Nonlocal Boundary Conditions

open access: yesAlgorithms, 2023
Integro-differential equations involving Volterra and Fredholm operators (VFIDEs) are used to model many phenomena in science and engineering. Nonlocal boundary conditions are more effective, and in some cases necessary, because they are more accurate ...

Coercivity estimates for integro-differential operators [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2020
We provide a general condition on the kernel of an integro-differential operator so that its associated quadratic form satisfies a coercivity estimate with respect to the $H^s$-seminorm.

Integro-differential polynomials and operators [PDF]

open access: yesProceedings of the twenty-first international symposium on Symbolic and algebraic computation, 2008
We propose two algebraic structures for treating integral operators in conjunction with derivations: The algebra of integro-differential polynomials describes nonlinear integral and differential operators together with initial values. The algebra of integro-differential operators can be used to solve boundary problems for linear ordinary differential ...

L-operator integro-differential inequality for dissipativity of stochastic integro-differential equations [PDF]

open access: yesMathematical Inequalities & Applications, 2011
In this paper, Ito stochastic integro-differential equations are considered. By establishing an L -operator integro-differential inequality and using the properties of M -cone and stochastic analysis technique, we obtain some new sufficient conditions ensuring the exponential p -dissipativity of the stochastic integro-differential equations. An example

Generalization of the Regularization Method to Singularly Perturbed Integro-Differential Systems of Equations with Rapidly Oscillating Inhomogeneity

open access: yesAxioms, 2021
In this paper, we consider systems of singularly perturbed integro-differential equations with a rapidly oscillating right-hand side, including an integral operator with a slowly varying kernel.
