Abstract

By using canonical transformation technique, we convert the nonlinear weakly canonical fourth-order delay diﬀerential equations into strongly canonical equations. Then we apply oscillation results for canonical equations to get similar results for the studied equation. The significance and novelty of our results are illustrated via numerical examples.
