Bartušek, M.; Cecchi, M.; Došlá, Z.; Marini, M. Positive solutions of third order damped nonlinear differential equations. (English) Zbl 1224.34152 Math. Bohem. 136, No. 2, 205-213 (2011). Summary: We study solutions tending to nonzero constants for the third order differential equation with damping term \[ (a_1(t)(a_2(t)x'(t))')'+q(t)x'(t)+r(t)f(x(\varphi (t)))=0 \] in the case when the corresponding second order differential equation is oscillatory.
