Forced oscillation of nth-order nonlinear differential equations Original Research Article

Some new oscillation criteria for forced nonlinear equations of the form View the MathML source , are established. We impose no restriction on the forcing term f(t) as those assumed in [1,2]. We further employ the technique presented here to establish new oscillation criteria for forced nonlinear neutral equations of the form View the MathML source , where λ > 1 and σ > 1.
