| Abstract: | In this paper, Wenobtain some necessary and sufficient conditions of the asymptotic and oscillatory behavior of solutions for functional differential ineguali-ties by comparison theorem. We apply the necessary and snfficient conditions to Higher-Ordcr neutral functional differential eguations. As corollary,we prove twe conjectures made by G. Ladas and y.G.sficas. |
