摘要：In this work, we present sufficient conditions for oscillation of all solutions of a second-order functional differential equation. We consider two special cases when $\gamma >\beta $ and $\gamma <\beta $ . This new theorem complements and improves a number of results reported in the literature. Finally, we provide examples illustrating our results and state an open problem.
