Bimodule and twisted representation of vertex operator algebras (Q283063)

If \(V\) is a vertex operator algebra with a finite order automorphism \(g\), Zhu constructed an associative algebra \(A_g(V)\). A generalization \(A_{g,n}(V)\) was later defined. In this paper the authors construct a bimodule \(\mathbf{A}_{g,n}(M)\) for the algebra \(A_{g,n}(V)\) and any admissible \(V\)-module \(M\). They study the structure of such bimodules and establish their connection with the space of intertwining operators.
