关于映射的同伦分类

On the homotopy classification of maps

Samson Saneblidze

摘要:

当诱导积分上同调同态平凡时,我们建立了拓扑空间的映射$f:X\to Y$为零同伦的条件,其中之一是:$H^*(X)$和$π_*(Y)$无挠,$H^*(Y)$为多项式.

英文摘要:

We establish certain conditions which imply that a map $f:X\to Y$ of topological spaces is null homotopic when the induced integral cohomology homomorphism is trivial; one of them is: $H^*(X)$ and $π_*(Y)$ have no torsion and $H^*(Y)$ is polynomial.
