ON GALOIS GROUPS FOR NON-IRREDUCIBLE INCLUSIONS OF SUBFACTORS

  • Published : 1999.01.01

Abstract

We apply sector theory to obtain some characterization on Gaois groups for subfactors. As an example of a non-irreducible inclusion of small index, a locally trivial inclusion arising from an automorphism is considered and its Galois group is completely determined by using sector theory.
