Cayley图同构于立方体的群

On groups with Cayley graph isomorphic to a cube

Colin Hagemeyer, Richard Scott

摘要:

我们说群G是立方体群,如果它是由一组对合生成的,使得对应的Cayley图Cay(G,S)同构于立方体。等价地,G是一个立方体群,如果它作用在一个立方体上,使得作用在顶点上是简单传递的,并且边稳定子都是非平凡的。立方体上的作用扩展为正交线性作用,我们称之为几何表示。证明了立方群的一个组合分解为2-子群的乘积,并证明了其几何表示总是可约的。

英文摘要:

We say that a group G is a cube group if it is generated by a set S of involutions such that the corresponding Cayley graph Cay(G,S) is isomorphic to a cube. Equivalently, G is a cube group if it acts on a cube such that the action is simply-transitive on the vertices and the edge stabilizers are all nontrivial. The action on the cube extends to an orthogonal linear action, which we call the geometric representation. We prove a combinatorial decomposition for cube groups into products of 2-element subgroup, and show that the geometric representation is always reducible.
