报告摘要：
This talk will report our recent progress on the study of Galois group Gal(A/V) for vertex operator algebras A and a conformal subalgebra V. It is established that if V is a nice VOA then Gal (A/V) is a finite group. Moreover, each element of Gal(A/V) can be realized as certain $A$-module category in the categorical setting. This is a joint work with Richard Ng, Li Ren and Feng Xu.
