Positive solutions of integrodifferential equations [PDF]

International Journal of Stochastic Analysis, 1992
Integrodifferential equations of the forms urn:x-wiley:20903332:media:ista345783:ista345783-math-0001 are considered, where K ∈ C([0, ∞), [0, ∞)), p ∈ C([0, ∞), [0, ∞)) and q ∈ C((−∞, ∞), [0, ∞)). Necessary conditions and also sufficient conditions for the existence of positive solutions are established.

Approximations of solutions to retarded integrodifferential equations

Electronic Journal of Differential Equations, 2004
In this paper we consider a retarded integrodifferential equation and prove existence, uniqueness and convergence of approximate solutions. We also give some examples to illustrate the applications of the abstract results.

Chebyshev Collocation Method for Parabolic Partial Integrodifferential Equations

Advances in Mathematical Physics, 2016
An efficient technique for solving parabolic partial integrodifferential equation is presented. This technique is based on Chebyshev polynomials and finite difference method. A priori error estimate for the proposed technique is deduced.

Quasilinear integrodifferential Bernoulli-type equations

Journal of Physics: Conference Series, 2019
Abstract The equations considered in this article have the form in which the time derivative of the unknown function is expressed as a double integral over the space variables of a weighted quadratic expression of the sought function. The domain of integration is unbounded and does not depend on time but depends on the space variable. We

Asymptotic estimates of the solution for a singularly perturbed Cauchy problem

Қарағанды университетінің хабаршысы. Математика сериясы
The article focuses on the initial problem for a third-order linear integro-differential equation with a small parameter at the higher derivatives, assuming that the roots of the additional characteristic equation have opposite signs.

Existence of solutions for quasilinear delay integrodifferential equations with nonlocal conditions

Electronic Journal of Differential Equations, 2009
We prove the existence and uniqueness of mild and classical solution to a quasilinear delay integrodifferential equation with nonlocal condition. The results are obtained by using $C_0$-semigroup and the Banach fixed point theorem.
