Independence of twisted representations and Zhu's algebras under inner automorphisms
Independence of twisted representations and Zhu's algebras under inner automorphisms
Let be a vertex operator algebra, let be an automorphism of , and let be an inner automorphism of . Consider lower bounded logarithmic -twisted and -twisted modules, together with their twisted Zhu's algebras.
Inner-automorphism invariance conjecture. There is a one-to-one correspondence between the simple objects in the category of lower bounded logarithmic -twisted modules and the simple objects in the category of lower bounded logarithmic -twisted modules, and
Thus both the simple twisted-module theory and the twisted Zhu's algebra should be independent of the inner automorphism used to modify . The preceding result establishes this invariance in the affine vertex-operator-algebra setting considered in the paper; the assertion for a general vertex operator algebra and automorphism is left open.
