Integral criteria of oscillation for a third order linear differential equation
Oscillation theorems for third order nonlinear differential equations
Criteria of property for third order superlinear differential equations
An integral condition of oscillation for equation with nonnegative coefficients
Our aim in this paper is to obtain a new oscillation criterion for equation with a nonnegative coefficients which extends and improves some oscillation criteria for this equation. In the special case of equation (*), namely, for equation , our results solve the open question of .
On a conjecture about an integral criterion for oscillation
We discuss an open question of Kiguradze and Chanturia about Property and Property for the equation . The proposed integral criterion is proved in a few cases.
