Interval oscillation of second-order Emden-Fowler neutral delay differential equations. <i>Electronic Journal of Differential Equations, 2007</i>(58), pp. 1-9.1072-6691https://hdl.handle.net/10877/14219Employing Riccati techniques and the integral averaging method, we establish interval oscillation criteria for the second-order Emden-Fowler neutral delay differential equation [|x′(t)|γ-1 x′(t)]′ + q1(t)|y(t - σ)|α-1 y(t - σ) + q2(t)|y(t - σ)|β-1 y(t - σ) = 0, where t ≥ t0 and x(t) = y(t) + p(t)y(t - τ). The criteria obtained here are different from most known criteria in the sense that they are based on information only on a sequence of subintervals of [t0, ∞), rather than on the whole half-line. In particular, two interesting examples that illustrate the importance of our results are included.Text9 pages1 file (.pdf)enAttribution 4.0 InternationalInterval oscillationNeutral delay differential equationEmden-FowlerRiccati techniqueIntegral averaging methodArticleThis work is licensed under a Creative Commons Attribution 4.0 International License.
