$EE_8$ -格与二面体群

$EE_8$-lattices and dihedral groups

Robert L. Griess, Ching Hung Lam

摘要:

我们分类积分无根格是$EE_8$ -格(等距的$\sqrt 2$倍的$E_8$ -格)和定义二面体群的订单小于或等于12对的总和。其中大部分可以在Leech晶格中看到。我们的分类有助于理解格型顶点算子代数上的Miyamoto对合,并给出Glauberman-Norton月光理论中出现的二面体群的上下文.

英文摘要:

We classify integral rootless lattices which are sums of pairs of $EE_8$-lattices (lattices isometric to $\sqrt 2$ times the $E_8$-lattice) and which define dihedral groups of orders less than or equal to 12. Most of these may be seen in the Leech lattice. Our classification may help understand Miyamoto involutions on lattice type vertex operator algebras and give a context for the dihedral groups which occur in the Glauberman-Norton moonshine theory.
