点传递三次部分立方体的分类
Classification of vertex-transitive cubic partial cubes
摘要:
部分立方体是可等距嵌入超立方体的图。本文证明了每一个三次顶点可迁部分立方体同构于下列图之一:$K_2 \, \square \, C_{2n}$,对于某些$n\geq 2$,广义Petersen图$G(10,3)$,立方置换面体,截顶立方八面体或截顶二十面体.这种分类是Brešar等人结果的推广。从2004年开始,它包含了所有的立方,距离正则的部分立方体(Weichsel,1992),并对所有立方部分立方体的分类做出了贡献。
英文摘要:
Partial cubes are graphs isometrically embeddable into hypercubes. In this paper it is proved that every cubic, vertex-transitive partial cube is isomorphic to one of the following graphs: $K_2 \, \square \, C_{2n}$, for some $n\geq 2$, the generalized Petersen graph $G(10,3)$, the cubic permutahedron, the truncated cuboctahedron, or the truncated icosidodecahedron. This classification is a generalization of results of Brešar et al.~from 2004 on cubic mirror graphs, it includes all cubic, distance-regular partial cubes (Weichsel, 1992), and presents a contribution to the classification of all cubic partial cubes.
