Lower Bounds of Periods of Periodic Solutions for a Class of Differential Equations with Variable Delays

Based on generalized Wirtinger's inequality, periods of periodic solutions of the nonautonomous differential equations with variable delays are investigated. Based on Hölder inequality, lower bounds of periods of periodic solutions for a class of functional differential equations with variable...
