Regular vertex operator subalgebras and compressions of intertwining operators

[摘要] Let V be a vertex operator subalgebra of U. Assume that U, V, and its commutant V-c in Uare CFT-type, self-dual, and regular VOAs. Assume also that the double commutant V-cc equals V. We prove that any intertwining operator of Vis a compression of intertwining operators of U. (C) 2020 Elsevier Inc. All rights reserved.
