1) homotopic noninvariant property
同伦不变性做出了推广
2) equivariant homotopy pushout
等变同伦推出
3) homotopy invariance
同伦不变性
1.
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 。
4) homotopy pushouts
同伦推出
1.
Using homotopy pushouts to characterize homotopy epimorphisms, we have the result as follows: If f: X→ Y is a homotopy epimorphism, H is a normal subgroup of π1Y, then the lifting f: X(f#-l(H)) → Y(H) is also a homotopy epimorphism.
本文在点标道路连通ＣＷ空间的同伦范畴中，利用同伦推出示性了同伦满态，得出了若ｆ：Ｘ－Ｙ是同伦满态，则对π１Ｙ的任一正规子群Ｈ，升腾映射ｆ：Ｘ（ｆ－１＃（Ｈ））→■（Ｈ）也是同伦满态。
