On the Volterra property of a boundary problem with integral gluing condition for mixed parabolic-hyperbolic equation [PDF]

open access: yes, 2013
In the present work we consider a boundary value problem with gluing conditions of integral form for parabolic-hyperbolic type equation. We prove that the considered problem has the Volterra property.

Existence Theorem for Integral and Functional Integral Equations with Discontinuous Kernels

open access: yesAbstract and Applied Analysis, 2012
Existence of extremal solutions of nonlinear discontinuous integral equations of Volterra type is proved. This result is extended herein to functional Volterra integral equations (FVIEs) and to a system of discontinuous VIEs as well.

Solutions of a quadratic Volterra–Stieltjes integral equation in the class of functions converging at infinity

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2018
The paper deals with the study of the existence of solutions of a quadratic integral equation of Volterra–Stieltjes type. We are looking for solutions in the class of real functions continuous and bounded on the real half-axis $\mathbb{R}_+$ and ...

Equivalence of Volterra integral equations [PDF]

open access: yesČasopis pro pěstování matematiky, 1986
The equivalence of two integral (integrodifferential) equations is investigated, one being a standard linear Volterra integral equation and the other its perturbation by a nonlinear integral term involving a multifunction.

An approach of extrapolation methods for the solution of nonlinear Volterra–Fredholm integral equations of the second kind [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization
This study presents the process of using extrapolation methods to solve the nonlinear Volterra–Fredholm integral equations of the second kind. To do this, by approximating the integral terms contained in equations by a quadrature rule, the nonlinear ...

Numerical Study of Two-Dimensional Volterra Integral Equations by RDTM and Comparison with DTM

open access: yesAbstract and Applied Analysis, 2013
The two-dimensional Volterra integral equations are solved using more recent semianalytic method, the reduced differential transform method (the so-called RDTM), and compared with the differential transform method (DTM).
