Oscillation theorems for neutral differential equations of higher order. (English) Zbl 1057.34074

Summary: We present some new oscillatory criteria for \(n\)th-order neutral differential equations of the form \((x (t) \pm p (t) x [\tau (t)])^{(n)} + q (t) x [\sigma (t)] = 0\). The obtained results extend and improve a number of existing criteria.
