On bounded solutions of differential systems

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2022
The question of the existence of bounded solutions on an infinite interval of a linear inhomogeneous system of ordinary differential equations in a finite-dimensional space is considered. The study of bounded solutions of systems of ordinary differential

Volterra integro-differential equations and infinite systems of ordinary differential equations

open access: yesMathematical and Computer Modelling, 2005
The authors develop the reduction method to establish a duality between finite-dimensional systems of integro-differential equations with the Hilbert-Schmidt kernel and countable systems of ordinary differential equations. This allows the use of known results for the countable systems of differential equations to study the properties of solutions of ...

Infinite Systems of Hyperbolic Functional Differential Equations [PDF]

open access: yesUkrainian Mathematical Journal, 2003
Summary: We consider initial-value problems for infinite systems of first-order partial functional differential equations. The unknown function is the functional argument in equations and the partial derivations appear in the classical sense. A theorem on the existence of a solution and its continuous dependence upon initial data is proved.

Backward doubly stochastic differential equations with infinite time horizon [PDF]

open access: yes, 2012
summary:We give a sufficient condition on the coefficients of a class of infinite horizon backward doubly stochastic differential equations (BDSDES), under which the infinite horizon BDSDES have a unique solution for any given square integrable terminal

On the existence of solutions for a multi-singular pointwise defined fractional system

open access: yesAdvances in Difference Equations, 2020
One of best ways for increasing our abilities in exact modeling of natural phenomena is working with a singular version of different fractional differential equations. As is well known, multi-singular equations are a modern version of singular equations.
