度量图的限制配置空间的同胚与同伦类型

Homeomorphism and Homotopy Types of Restricted Configuration Spaces of Metric Graphs

James Dover, Murad Özaydın

摘要:

对于有限的,连接的度量图,我们认为空间的配置的n个点在伽玛与约束参数r规定的最小距离允许每对点之间。这些受限的配置空间在拓扑机器人学中自然出现。在本文中,我们研究了同伦,同胚,和这些空间的参数空间r上的合痕类型,并提供了一个多项式上界(在伽玛的边数)的合痕类型的数量。

英文摘要:

For Gamma a finite, connected metric graph, we consider the space of configurations of n points in Gamma with a restraint parameter r dictating the minimum distance allowed between each pair of points. These restricted configuration spaces come up naturally in topological robotics. In this paper, we study the homotopy, homeomorphism, and isotopy types of these spaces over the space of parameters r and provide a polynomial upper bound (in the number of edges of Gamma) for the number of isotopy types.
