EXISTENCE OF NONOSCILLATORY SOLUTIONS FOR SECOND-ORDER NONLINEAR NEUTRAL DIFFERENTIAL EQUATIONS WITH VARIABLE DELAYS

Year 2019, Volume: 9 Issue: 3, 589 - 596, 01.09.2019

Abstract

In this work, an attempt is made to discuss the existence of nonoscillatory solutions of second order nonlinear neutral di erential equations with variable delays. The main tools are Lebesgue's dominated convergence theorem and Banach contraction principle to obtain new sucient conditions for the existence of nonoscillatory solutions. This problem is considered in various ranges of the neutral coecient. Further, two illustrative examples showing applicability of the new results are included.
