Free integro-differential algebras and Groebner-Shirshov bases [PDF]

open access: yes, 2014
The notion of commutative integro-differential algebra was introduced for the algebraic study of boundary problems for linear ordinary differential equations. Its noncommutative analog achieves a similar purpose for linear systems of such equations.

An implicit system of delay differential algebraic equations from hydrodynamics

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2023
Direct spring operated pressure relief valves connected to a constantly charged vessel and a downstream pipe have a complex dynamics. The vessel-valve subsystem is described with an autonomous system of ordinary differential equations, while the presence

The Lie group Euler methods of multibody system dynamics with holonomic constraints

open access: yesAdvances in Mechanical Engineering, 2018
The Euler methods on Lie group are developed for the differential–algebraic equations of multibody system dynamics with holonomic constraints. The implicit Euler method is used to solve the differential–algebraic equations as Euler–Lagrange equations on ...

Algebraic structure of space and field

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2001
We investigate an algebraic structure of the space of solutions of autonomous nonlinear differential equations of certain type. It is shown that for these equations infinitely many binary algebraic laws of addition of solutions exist.

A Numerical Method using Collocation Approach for the Solution of Volterra-Fredholm Integro-Differential Equations

open access: yesAfrican Scientific Reports, 2022
This paper consider collocation approach for the numerical solution of Volterra-Fredholm Integro-differential equation using collocation method. We transformed the problem into a system of linear algebraic equations and matrix inversion is adopted to ...
