Abstract: This work is concerned with the study of oscillation of a class of fourth-order neutral differential equations with unbounded delay. Sufficient conditions are obtained for oscillation and they are classified as C−1, C0 and C1 type oscillatory criteria.
Keywords: delay; functional differential equations; oscillation; nonlinear differential equations; neutral differential equations.
