Let $V_L$ be the lattice vertex operator algebra associated with the 128-dimensional Barnes–Wall lattice, and let $E(7)$ act on $V_L$. A holomorphic conformal field theory has cent…

Trivial-anomaly conjecture. For the orbifold of the $d=128$ Barnes–Wall lattice VOA by $E(7)$, $\omega$ is trivial. A trivial anomaly is necessary for constructing a holomorphic ex…
