Existence of periodic solutions to nonlinear differential equations of third order with multiple deviating arguments. (English) Zbl 1251.34087
Summary: We establish 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 used here.
