They establish some new oscillation criteria via comparison with higher-order linear delay differential inequalities as well as with first-order linear delay differential equations whose oscillatory characters are known. Examples are provided to illustrate the theorems.", keywords = "oscillatory behavior, neutral differential equation, even-order", issn = "1232-9274" }
