## Asymptotic properties of the third order delay differential equations.(English)Zbl 0840.34076

The author using comparison techniques investigates the oscillatory and nonoscillatory properties of the third-order delay differential equation $$y'''(t)- p(t) y'(t)+ g(t) y(\tau(t))= 0$$. Several criteria are given.
