Lattice vertex algebras over a field of positive characteristic: degenerate cases

Robert L. Griess, Ching Hung Lam

A vertex operator algebra $V_{L}$ associated with a positive definite even lattice $L$ has a standard integral form, which we denote it by $V_{L, Z}$ . If $F$ is a field of c…

Permutation orbifolds and simple current extensions

Ching Hung Lam, Nina Yu

In this article, we study permutation orbifolds and simple current extensions in the framework of vertex operator (super)algebras. We extend the construction of permutation-twisted…
