关于欧拉示性数的乘性

On the multiplicativity of the Euler characteristic

John R. Klein, Cary Malkiewich, Maxime Ramzi

摘要:

本文给出了双控制空间纤维序列的欧拉示性数是乘性的两个证明。这等价于证明Becker-Gottlieb转移在$π_0$上是函式的。

英文摘要:

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 $π_0$.
