AI总结:
本文研究了一般化佩特森图的拓扑对称群,确定了所有可能的对称群形式,排除了例外图P(12,5)和P(24,5)。
摘要:
图Γ在S³中的嵌入的拓扑对称群TSG(Γ)是图的自同构群的子群,由(S³,Γ)的同胚诱导。如果我们限制在保持定向的同胚,则得到保持定向的拓扑对称群TSG_+(Γ)。在本文中,我们确定所有可能的TSG(Γ)或TSG_+(Γ)组,对于某些一般化佩特森图的嵌入Γ,除了例外图P(12,5)和P(24,5)(将在另一篇论文中讨论)之外。
英文摘要:
The topological symmetry group $\mathrm{TSG}(Γ)$ of an embedding $Γ$ of a graph in $S^3$ is the subgroup of the automorphism group of the graph which is induced by homeomorphisms of $(S^3,Γ)$. If we restrict to orientation preserving homeomorphisms then we obtain the orientation preserving topological symmetry group $\mathrm{TSG}_+(Γ)$. In this paper we determine all groups that can be $\mathrm{TSG}(Γ)$ or $\mathrm{TSG}_+(Γ)$ for some embedding $Γ$ of a generalized Petersen graph other than the exceptional graphs $P(12,5)$ and $P(24, 5)$ (which will be addressed in a separate paper.
