We study asymptotic properties of solutions of the system of differential equations of neutral type.

Oscillation of second order neutral delay differential equations

J. Džurina, D. Hudáková (2009)

Mathematica Bohemica

Similarity:

We establish some new oscillation criteria for the second order neutral delay differential equation ${[r (t) | [x (t) + p (t) x [τ (t)]]}^{'} {|^{α - 1} {[x (t) + p (t) x [τ (t)]]}^{'}]}^{'} + q (t) f (x [σ (t)]) = 0 .$ The obtained results supplement those of Dzurina and Stavroulakis, Sun and Meng, Xu and Meng, Baculíková and Lacková. We also make a slight improvement of one assumption in the paper of Xu and Meng.
