In this paper,the homotopy invariance of Leray-Schauder degr ee was used for studying the existence of solutions of two-point boundary value pr oblems for a class of semilinear second order ordinary differential equations wh ich satisfies the condition that the nonlinear perturbation term asymptotic grow s uniformly.
本文利用Leray -Schauder度的同伦不变性 ,在非线性扰动项满足渐进一致性增长条件下 ,研究了一类半线性二阶常微分方程两点边值问题的解的存在性 ,给出了解存在的一组充分条件 。
Simplicial homology group is a topological invariant,and is also a homotopy type invariant.
单纯同调群是拓扑不变量,也是伦型不变量,也就是说如果两个拓扑空间同伦等价而不同胚,那么它们的各维同调群同构,就不能用同调群来区别这两个空间。
