A note on the oscillation of second order differential equations

Hishyar Kh. Abdullah (2004)

Czechoslovak Mathematical Journal

We give a sufficient condition for the oscillation of linear homogeneous second order differential equation $y^{''} + p (x) y^{'} + q (x) y = 0$ , where $p (x), q (x) \in C [α, \infty)$ and $α$ is positive real number.

A remark on Nehari-type oscillation criteria for self-adjoint linear differential equations

Ondřej Došlý, Frank Fiedler (1991)

Commentationes Mathematicae Universitatis Carolinae

Oscillation criteria of Nehari-type for the equation ${(- 1)}^{n} {(x^{α} y^{(n)})}^{(n)} + q (x) y = 0$ , $α \in 𝐑$ , are established. These criteria impose no sign restriction on the function $q (x)$ and generalize some recent results of the second author.
