Third and Higher Order NFPA Twisted Constructions of Conformal Field Theories from Lattices


الملخص بالإنكليزية

We investigate orbifold constructions of conformal field theories from lattices by no-fixed-point automorphisms (NFPAs) $Z_p$ for $p$ prime, $p>2$, concentrating on the case $p=3$. Explicit expressions are given for most of the relevant vertex operators, and we consider the locality relations necessary for these to define a consistent conformal field theory. A relation to constructions of lattices from codes, analogous to that found in earlier work in the $p=2$ case which led to a generalisation of the triality structure of the Monster module, is also demonstrated.
