格顶点代数的共形子代数

Conformal subalgebras of lattice vertex algebras

Michael Roitman

摘要:

本文在一定的限制条件下,对格顶点超代数$V_Λ$中对应于整数格$Λ$的所有齐次共形子代数$\goth L$进行了分类.我们要求$\goth L$是由几乎有限根系$Δ\subset Λ$分次的,并且$\goth L$在Heisenberg共形代数$\goth H\subset V_Λ$的作用下是稳定的.我们还描述了这些子代数的根系。这种分类的关键成分是一个无穷型共形代数$\goth K$,它是由一个Jordan共形三元系$\goth J$通过Tits-Kantor-Koeher构造而得的。在费米子顶点超代数$V_\Z$中实现了$\goth K$的中心扩张$\^{\goth K}$,从而扩展了玻色子-费米子对应.

英文摘要:

In this paper we classify, under certain restrictions, all homogeneous conformal subalgebras $\goth L$ of a lattice vertex superalgebra $V_Λ$ corresponding to an integer lattice $Λ$. We require that $\goth L$ is graded by an almost finite root system $Δ\subset Λ$ and that $\goth L$ is stable under the action of the Heisenberg conformal algebra $\goth H\subset V_Λ$. We also describe the root systems of these subalgebras. The key ingredient of this classification is an infinite type conformal algebra $\goth K$ obtained by the Tits-Kantor-Koeher construction from a certain Jordan conformal triple system $\goth J$. We realize a central extension $\^{\goth K}$ of $\goth K$ inside the fermionic vertex superalgebra $V_\Z$, thus extending the bozon-fermion correspondence.
