| Abstract: |
| In this paper, we study the vibration problem of third order neutral differential equations with distributed delays. By using Riccati transform technique and integral averaging method, we obtain a criterion for equations with all solutions oscillating or converging to zero. An example is given to illustrate the application of the example. |
