摘要
Oscillatory property of solutions of the second order differential equation with an "integrally small" coefficient were studied in Refs. [1, 2], in which the corresponding results were improved in [3], but we have not yet seen any oscillation result about the second order functional differential equation with an "integrally small" coefficient. The aim of this note is to show some oscillatory theorems.We consider the following second order functional differential
