Discrete First-Order Three-Point Boundary Value Problem

M. Mohamed, H. B. Thompson, M. S. Jusoh, K. Jusoff


We study difference equations which arise as discrete approximations to three-point boundary value problems for systems
of first-order ordinary differential equations. We obtain new results of the existence of solutions to the discrete problem by
employing Euler’s method. The existence of solutions are proven by the contraction mapping theorem and the Brouwer
fixed point theorem in Euclidean space. We apply our results to show that solutions to the discrete problem converge to
solutions of the continuous problem in an aggregate sense. We also give some examples to illustrate the existence of a
unique solution of the contraction mapping theorem.
