拓扑Reeb空间的组合模型

Combinatorial models for topological Reeb spaces

Paul Trygsland

摘要:

现今有两种截然不同的方法来研究莫尔斯理论:平滑的和离散的。我们建议通过将所有相关的截面集合在一个拓扑范畴中来研究一个实值函数。从这个角度出发,介绍了分层空间上的Reeb函数,包括光滑和组合的例子。由于采取了单纯方法,该理论带有一个计算(广义)同调的谱序列。我们还模型的同伦类型的Reeb图/拓扑Reeb空间作为单纯集,这是组合的性质,而不是典型的描述商空间。

英文摘要:

There are two rather distinct approaches to Morse theory nowadays: smooth and discrete. We propose to study a real valued function by assembling all associated sections in a topological category. From this point of view, Reeb functions on stratified spaces are introduced, including both smooth and combinatorial examples. As a consequence of the simplicial approach taken, the theory comes with a spectral sequence for computing (generalized) homology. We also model the homotopy type of Reeb graphs/ topological Reeb spaces as simplicial sets, which are combinatorial in nature, as opposed to the typical description in terms of quotient spaces.
