Ising vectors in the vertex operator algebra $V_{\Lambda }^{+}$ associated with the Leech lattice $\Lambda$

Ching Hung Lam, Hiroki Shimakura

In this article, we study the Ising vectors in the vertex operator algebra $V_{\Lambda }^{+}$ associated with the Leech lattice $\Lambda$. The main result is a characterization of the Ising vectors…
