Oscillation results for second-order neutral differential equations of mixed type
Abstract
Some oscillation theorems are established for the
second-order linear neutral differential equations of mixed type
$$
\left(r(t)[x(t)+p_1(t)x(t-\sigma_1)+p_2(t)x(t+\sigma_2)]'\right)'+q_1(t)x(t-\sigma_3)
+q_2(t)x(t+\sigma_4)=0.
$$
Several examples are also provided to illustrate the main results.
