چکیده
|
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 delays are obtained by a simple method. © 2013 xin-ge liu and mei-lan tang.
