对角排列的同伦分解

Homotopy decomposition of diagonal arrangements

Daisuke Kishimoto, Kouyemon Iriye

摘要:

给定一个空间$X$和一个具有$m$ -顶点的单纯复形$K$,定义了$X^m$的部分对角子空间的排列,称为对角排列.我们分解了$2(dim K + 1) < m$时对角排列的悬挂,推广了Labassi的结果.作为推论,当$X$是闭连通流形时,我们计算了补图的欧拉示性数.

英文摘要:

Given a space $X$ and a simplicial complex $K$ with $m$-vertices, the arrangement of partially diagonal subspaces of $X^m$, called the dragonal arrangement, is defined. We decompose the suspension of the diagonal arrangement when $2(dim K + 1) < m$, which generalizes the result of Labassi. As a corollary, we calculate the Euler characteristic of the complement when $X$ is a closed connected manifold.
