The existence and approximation of the periodic solution of a system of nonlinear differential-differential equations of the first order with independent variable delay with boundary conditions [PDF]

open access: yesمجلة التربية والعلم, 2007
In this paper we study the existence and approximation of the solutions for some systems of nonlinear integro-differential equations with having retarded arguments and boundary conditions. The numerical–analytic method has been used to study the periodic

Periodic boundary value problem for second order integro‐ordinary differential equations with general kernel and Carathéodory nonlinearities [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
We study the existence of solutions for the periodic boundary value problem for some second order integro‐differential equations with a general kernel. Also we develop the monotone method to approximate the extremal solutions of the problem.

Symbolic Analysis for Boundary Problems: From Rewriting to Parametrized Groebner Bases [PDF]

open access: yes, 2010
We review our algebraic framework for linear boundary problems (concentrating on ordinary differential equations). Its starting point is an appropriate algebraization of the domain of functions, which we have named integro-differential algebras.
