Some New Oscillation Results for Fourth-Order Neutral Differential Equations with Delay Argument
The aim of this paper is to study the oscillatory properties of 4th-order neutral differential equations. We obtain some oscillation criteria for the equation by the theory of comparison. The obtained results improve well-known oscillation results in the literate. Symmetry plays an important role in...
