Summary: We study necessary and sufficient conditions for the oscillation of the third-order nonlinear ordinary differential equation with damping term and deviating argument
Motivated by the work of I. T. Kiguradze [Differ. Uravn. 28, No. 2, 207–219 (1992; Zbl 0768.34018)], the existence and asymptotic properties of nonoscillatory solutions are investigated in case when the differential operator is oscillatory.
