单纯高度函数的截面复形

Section complexes of simplicial height functions

Melvin Vaupel, Erik Hermansen, Paul Trygsland

摘要:

本文发展了单纯形高度函数的截面理论。在这个理论的核心是部分复杂,这是组装从更高的部分空间。后者以组合的方式对沿着高度的流线及其同伦进行编码。截面复形有一个相关的谱序列,它计算高度函数域的同调。我们从谱序列中提取Reeb复合物。这些提供了同源生成器如何沿着高度水平流动的一阶近似。我们的理论特别是模型的拓扑截面空间的分段线性函数在一个完全组合的方式。

英文摘要:

A theory of sections of simplicial height functions is developed. At the core of this theory lies the section complex, which is assembled from higher section spaces. The latter encode flow lines along the height, as well as their homotopies, in a combinatorial way. The section complex has an associated spectral sequence, which computes the homology of the height functions domain. We extract Reeb complexes from the spectral sequence. These provide a first order approximation of how homology generators flow along height levels. Our theory in particular models topological section spaces of piecewise linear functions in a completely combinatorial way.
