Oscillation criteria for second-order neutral equations with distributed deviating arguments (Q1767910)

The paper deals with the second-order neutral differential equation \[ [a(t)(x(t)+c(t)x(t-\tau))']'+\int_a^bp(t,\xi)x[g(t,\xi)]d\sigma(\xi)=0,\quad t\geq t_0,\tag{1} \] where \(\tau >0\) is a constant. The author presents several sufficient conditions for equation (1) to be oscillatory. An example is given for illustration.
