Oscillation for second-order differential equations with delay. <i>Electronic Journal of Differential Equations, 2018</i>(96), pp. 1-9.1072-6691https://hdl.handle.net/10877/15263We establishing monotonic properties of non-oscillatory solutions, and oscillation criteria for the second-order delay differential equation y″(t) + p(t)y(τ(t)) = 0. The criteria obtained fulfil the gap in the oscillation theory and essentially improves the earlier ones. The progress is illustrated via Euler's differential equation. Moreover, we provide upper and lower bounds for the non-oscillatory solutions.Text9 pages1 file (.pdf)enAttribution 4.0 InternationalSecond order differential equationDelay argumentOscillationMonotonic propertiesArticle
