An integral condition of oscillation for equation $y^{'''} + p (t) y^{'} + q (t) y = 0$ with nonnegative coefficients

Anton Škerlík (1995)

Archivum Mathematicum

Our aim in this paper is to obtain a new oscillation criterion for equation $y^{'''} + p (t) y^{'} + q (t) y = 0$ with a nonnegative coefficients which extends and improves some oscillation criteria for this equation. In the special case of equation (*), namely, for equation $y^{'''} + q (t) y = 0$ , our results solve the open question of $C h a n t u r i y a$ .

An oscillatory half-linear differential equation

Árpád Elbert, Takaŝi Kusano, Tomoyuki Tanigawa (1997)

Archivum Mathematicum

A second-order half-linear ordinary differential equation of the type $(| y^{'} |^{α - 1} y^{'})^{'} + α q (t) {| y |}^{α - 1} y = 0 (1)$ is considered on an unbounded interval. A simple oscillation condition for (1) is given in such a way that an explicit asymptotic formula for the distribution of zeros of its solutions can also be established.
