月光顶点算子代数的$E_8$ -方法

An $E_8$-approach to the moonshine vertex operator algebra

Hiroki Shimakura

摘要:

本文从顶点算子代数$V_{\sqrt2E_8}^+$的三个副本的张量积出发,研究了月光顶点算子代数,并用与$V_{\sqrt2E_8}^+$相关联的$V_{\sqrt2E_8}^+$上的二次空间来描述它.利用二次空间和正交群,证明了月光顶点算子代数的自同构群在与$V_{\sqrt2E_8}^+$的三个副本的张量积同构的所有满顶点算子子代数的集合上的传递性,并确定了这样的顶点算子子代数的稳定子.我们的方法是一个顶点算子代数的模拟“一个$E_8$ -方法的Leech格和康威集团”的Leepowsky和Meurman。此外,我们发现了月光顶点算子代数,Leech格和扩展的二进制Golay码之间的新的类比。

英文摘要:

In this article, we study the moonshine vertex operator algebra starting with the tensor product of three copies of the vertex operator algebra $V_{\sqrt2E_8}^+$, and describe it by the quadratic space over $\F_2$ associated to $V_{\sqrt2E_8}^+$. Using quadratic spaces and orthogonal groups, we show the transitivity of the automorphism group of the moonshine vertex operator algebra on the set of all full vertex operator subalgebras isomorphic to the tensor product of three copies of $V_{\sqrt2E_8}^+$, and determine the stabilizer of such a vertex operator subalgebra. Our approach is a vertex operator algebra analogue of "An $E_8$-approach to the Leech lattice and the Conway group" by Lepowsky and Meurman. Moreover, we find new analogies among the moonshine vertex operator algebra, the Leech lattice and the extended binary Golay code.
