考虑奇数阶常微分方程的反周期问题, 把问题先转化为求算子的不动点问题, 再利用拓扑度理论, 证明算子不动点的存在性, 从而得到所考虑问题解的存在性, 最后证明了解的惟一性. 相似文献

In this paper, we study the anti-periodic solutions for 2n-th order differential equations. By using the Schauder's fixed point theorem, we present some new results about the existence and uniqueness of anti-periodic solutions for 2n-th order differential equations. 相似文献

In this paper we investigate the homoclinic bifurcation properties near an eight-figure homoclinic orbit of co-dimension two of a planar dynamical system. The corresponding local bifurcation diagram is also illustrated by numerical computation. 相似文献
