警察与强盗中的拓扑方向

Topological directions in Cops and Robbers

Anthony Bonato, Bojan Mohar

摘要:

我们调查结果在拓扑图论的交叉点和游戏的警察和强盗,专注于结果,插图,和开放的问题,嵌入在一个表面上的图的警察数。在讨论了可平面图的一些结果之后,我们考虑了高亏格图。2001年,Schroeder证明了如果一个图有亏格$g,$,那么它的cop数至多为$g + 3.$。我们考虑了图在曲面上的捕获时间,并研究了图在非可定向曲面上的嵌入结果。我们提出了一个猜想的第二作者,此外,我们调查结果的懒惰警察数,有向图,僵尸和幸存者。

英文摘要:

We survey results at the intersection of topological graph theory and the game of Cops and Robbers, focusing on results, conjectures, and open problems for the cop number of a graph embedded on a surface. After a discussion on results for planar graphs, we consider graphs of higher genus. In 2001, Schroeder conjectured that if a graph has genus $g,$ then its cop number is at most $g + 3.$ While Schroeder's bound is known to hold for planar and toroidal graphs, the case for graphs with higher genus remains open. We consider the capture time of graphs on surfaces and examine results for embeddings of graphs on non-orientable surfaces. We present a conjecture by the second author, and in addition, we survey results for the lazy cop number, directed graphs, and Zombies and Survivors.
