• EXISTENCE OF POSITIVE SOLUTIONS OF SECOND ORDER NONLINEAR NEUTRAL DELAY DIFFERENCE EQUATIONS WITH FORCING TERM
Abstract
This paper deals with the existence of positive solutions of nonlinear neutral delay difference equations with positive and negative coefficients of the form
under the following assumption that
for various ranges of . By using Banach’s contraction mapping principle, some sufficient conditions are established for the existence of nonoscillatory solutions.
