算术群与仿射E8 Dynkin图

Arithmetic groups and the affine E8 Dynkin diagram

John F. Duncan

摘要:

几十年前,John McKay提出了仿射E8 Dynkin图的节点与Monster群中某些共轭类之间的对应关系。多亏了Monterrey Moonshine,这种对应关系可以被改写为将PSL 2的离散子群分配给仿射E8 Dynkin图的节点。本文的目的是给出一个解释后一个对应使用基本性质的小组PSL 2。我们还得到了一个超级类似的McKay的观察,其中共轭类的怪物被Conway的群-的自同构群的Leech格的共轭类取代。

英文摘要:

Several decades ago, John McKay suggested a correspondence between nodes of the affine E8 Dynkin diagram and certain conjugacy classes in the Monster group. Thanks to Monstrous Moonshine, this correspondence can be recast as an assignment of discrete subgroups of PSL2 to nodes of the affine E8 Dynkin diagram. The purpose of this article is to give an explanation for this latter correspondence using elementary properties of the group PSL2. We also obtain a super analogue of McKay's observation, in which conjugacy classes of the Monster are replaced by conjugacy classes of Conway's group -- the automorphism group of the Leech lattice.
