摘要
利用min-max原理的非变分形式,证明了共振下2k阶微分方程系统边值问题u(2k)(t)+∑kj=1Aju(2j-1)(t)+(-1)k-1 G(u,t)=e(t)周期解的存在惟一性问题.
A non-variational version of a max-min principle is extended, and some unique existence results for the periodic boundary value problem of the higher order nonconservative systems with resonance u^（2k）（t）＋Σj=1^k Aju^（2j-t）（t）＋（-1）^k-1↓ΔG（u,t）=e（t）are obtained.
