Asymptotic and oscillation properties of solutions of differential equations in the Canonical case

The existence of oscillatory solutions to fourth-order differential equations with multiple delays is investigated in this paper. The comparison method and the Riccati method are used to create new oscillation conditions. The results we have got, when compared to some studies in the literature, not only enhance the conditions for the oscillation of the examined equations, but they also expand some of the results that have already been published. Some examples are provided to illustrate the results.
