道路空间I:一个Menger型结果

Path spaces I: A Menger-type result

Hendrik Heine

摘要:

无限图是有限的,因为它们的点是通过有限路连接的。那么,有限图的无限推广会是什么样子呢?通常这个问题是回答的帮助下的拓扑结构,例如在案件的图形空间。在这里我们引入一个更组合的答案,我们称之为路空间,并证明了一个版本的门格尔定理.由于有许多拓扑路径类对象诱导道路空间,这个结果可以应用在各种设置.

英文摘要:

Infinite graphs are finitary in the sense that their points are connected via finite paths. So what would an infinitary generalization of finite graphs look like? Usually this question is answered with the aid of topology, e.g. in the case of graph-like spaces. Here we introduce a more combinatorial answer, which we call path space, and prove a version of Menger's theorem for it. Since there are many topological path-like objects which induce path spaces, this result can be applied in a variety of settings.
