In this paper, we consider the oscillation of nth-order neutral functional differential equations of mixed type with continuous delay of the form where Ξ΄ = Β±1, Ξ» = Β±1, Β΅ = Β±1, and p, q are continuous and periodic functions for t.
This paper discusses a class of first-order nonlinear neutral differential equations with variable coefficients and variable deviations. Sharp conditions are established for all solutions of the equations to be oscillatory. Linearized oscillation criteria of the equations are also given. (~) 2000 El
New oscillation criteria for nth-order functional differential equations of the form when g(t) is a retarded argument, i.e., g(t) < t and g(t) is an advanced argument, i.e., g(t) > t are established.
