摘要：Orbifold theory explores the structure of vertex operator algebras when finite groups act on them, with a particular focus on understanding the representation theory of the fixed point subalgebra. A key aspect of this field is permutation orbifolds, which study how the symmetric group acts on the n-fold tensor product of a vertex operator algebra. In this talk, I will present our recent results on the fusion product of twisted modules in permutation orbifolds. This work is a collaboration with C. Dong and F. Xu.
