Twisted representations of code vertex operator algebras (Q1305079)

\textit{M. Miyamoto} introduced a class of vertex operator algebras by gluing finite copies of the irreducible modules of the Virasoro algebra with central charge \(1/2\) [J. Algebra 179, 523-548 (1996; Zbl 0964.17021)]. He also studied untwisted irreducible representations of these algebras [J. Algebra 201, 115-150 (1998; Zbl 0908.17019)]. The author of this paper studies the \(g\)-twisted irreducible representations of these vertex operator algebras. In particular, he proves that the VOA is \(g\)-rational when \(g\) is an inner automorphism.
