Abstract
In this paper, oscillatory and asymptotic behaviour of solutions of a class of nonlinear fourth order neutral differential equations with several delay of the form for various ranges of p(t). Using Schauder's fixed point theorem, sufficient conditions are obtained for the existence of bounded positive solutions of (E). The results obtained in this paper generalize the results existing in the literature.
