Existence of Periodic Solutions to Nonlinear Differential Equations of Third Order with Multiple Deviating Arguments

الملخص EN

We establish certain new sufficient conditions which guarantee the existence of periodic solutions for a nonlinear differential equation of the third order with multiple deviating arguments.

Using the Lyapunov functional approach, we prove a specific theorem and provide an example to illustrate the theoretical analysis in this work and the effectiveness of the method utilized here.
