The Hyers-Ulam stability for nonlinear Volterra integral equations via a generalized Diaz-Margolis's fixed point theorem [PDF]

open access: yesarXiv, 2015
In this work, we prove an existence theorem of the Hyers-Ulam stability for the nonlinear Volterra integral equations which improves and generalizes Castro-Ramos theorem by using some weak conditions.

The Control Problem for a Heat Conduction Equation with Neumann Boundary Condition

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki
Previously, boundary control problems for a heat conduction equation with Dirichlet boundary condition were studied in a bounded domain. In this paper, we consider the boundary control problem for the heat conduction equation with Neumann boundary ...

Optimal control of Goursat-Volterra systems [PDF]

open access: yesarXiv, 2007
We analyze an optimal control problem for systems of integral equations of Volterra type with two independent variables. These systems generalize both, the hyperbolic control problems for systems of Goursat-Darboux type, and the optimal control of ordinary (i.e. with one independent variable) Volterra integral equations.

The approximate solution of Volterra integral equations

open access: yesJournal of Approximation Theory, 1975
AbstractHuffstutler and Stein and recently Bacopoulos and Kartsatos have dealt with the problem of best approximation by polynomials of the solutions of nonlinear differential equations. The purpose of the present paper is to generalize their results and to show that they can be established under a weaker set of conditions.

On the solution to a two-dimensional boundary value problem of heat conduction in a degenerating domain

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
The article considers a homogeneous boundary - value problem for the heat equation in the non - cylindrical domain, namely, in an inverted pyramid with a vertex at the origin of coordinates, two faces of which lie in coordinate planes.A solution to the ...
