M.J. Mardanov, Y.A. Sharifov, Humbet Aliyev, R.A. Sardarova


This article discusses the existence and uniqueness of solutions for the system of non-linear first order ordinary differential equations with multipoint boundary conditions. The Green function is constructed, and the problem is reduced to the equivalent integral equation. Existence and uniqueness of the solution to this problem is studied using the Banach contraction mapping principle and Schaefer’s fixed point theorem.


Multipoint boundary conditions, existence and uniqueness solutions, fixed point theorems, first order differential equation, Schaefer's fixed point theorem.
