More Effective Results for Testing Oscillation of Non-Canonical Neutral Delay Differential Equations
Keyword(s):
In this work, we address an interesting problem in studying the oscillatory behavior of solutions of fourth-order neutral delay differential equations with a non-canonical operator. We obtained new criteria that improve upon previous results in the literature, concerning more than one aspect. Some examples are presented to illustrate the importance of the new results.
