On fixity of arc-transitive graphs
收藏 引用
Science China Mathematics 2021年 第12期64卷 2603-2610页
作者: Florian Lehner Primoz Potocnik Pablo Spiga Institute of Discrete Mathematics Graz University of TechnologyGraz 8010Austria Faculty of Mathematics and Physics University of LjubljanaLjubljana 1000Slovenia Dipartimento di Matematica Pura e Applicata University of Milano-BicoccaMilano 20126Italy
The relative xity of a permutation group is the maximum proportion of the points xed by a non-trivial element of the group,and the relative xity of a graph is the relative xity of its automorphism group,viewed as a pe... 详细信息

Symmetry properties of Cayley graphs of small valencies on the alternating group A_5
收藏 引用
Science China Mathematics 2004年 第4期47卷 593-604页
作者: XU Mingyao XU Shangjin LMAM&School of Mathematical Sciences Peking UniversityBeijing 100871China
The normality of symmetry property of Cayley graphs of valencies 3 and 4 on the alternating group A5 is studied. We prove that all but four such graphs are normal;that A5 is not 5-CI. A complete classification of all ... 详细信息
