论文摘要
在这篇简短的论文中,我们给出了两个证据,表明欧拉的特征是乘法的,对于有限支配空间的纤维序列。这相当于证明Becker-Gottlieb的转移在$π_0$上起作用。
In this short paper, we give two proofs that the Euler characteristic is multiplicative, for fiber sequences of finitely dominated spaces. This is equivalent to proving that the Becker-Gottlieb transfer is functorial on $π_0$.
