光滑轨道的最小周期(周期)

Minimal Periods of Smooth Orbits

本文考虑动力系统 (dx)/(dt)=f(x),x∈E^n,得出其周期轨道x(t)的最小周期T>0满足: TC≥2π,其中,而且2π是最好的常数。

This paper deals with dynamical system E. We obtained an inequality: TC > 2 for any periodic solution x(t) with period T > 0 of this system, where C = max and 2 is the best such constant
