摘要💧：
Let V be a simple vertex algebra of countable dimension, G be a finite automorphism group of V and \sigma be a central element of G. For any finite set S of inequivalent irreducible \sigma-twisted modules such that S is invariant under the action of G, we establish a duality result of Schur-Weyl type for V^G and a semisimple associative algebra A_{\alpha}(G,S) on the sum of irreducible modules in S. In particular, any \sigma-twisted module is a direct sum of finitely many irreducible V^G-modules. We also obtain a quantum Galois correspondence for the action of G on V. This is joint work with Chongying Dong and Chao Yang.
