中对称型图

Medial symmetry type graphs

Isabel Hubard, Alen Orbanić, Tomaž Pisanski, María del Río Francos

摘要:

一个$k$ -轨道映射是一个映射,它的自同构群将标志集划分为$k$轨道。最近,Orbani ' c、Pellicer和Weiss研究了$k$的轨道图。本文利用对称型图对这一研究进行了推广,并对所有类型的$5$ -轨道映射以及所有自对偶的、正确的和不正确的$k$ -轨道映射与$k\leq 7$的对称型进行了分类.此外,我们确定,对于小值的$k$,所有类型的$k$轨道地图是中间的地图。自我二重性构成了这一追求的一个重要工具。

英文摘要:

A $k$-orbit map is a map with its automorphism group partitioning the set of flags into $k$ orbits. Recently $k$-orbit maps were studied by Orbani\' c, Pellicer and Weiss, for $k \leq 4$. In this paper we use symmetry type graphs to extend such study and classify all the types of $5$-orbit maps, as well as all self-dual, properly and improperly, symmetry type of $k$-orbit maps with $k\leq 7$. Moreover, we determine, for small values of $k$, all types of $k$-orbits maps that are medial maps. Self-dualities constitute an important tool in this quest.
