Solitons in Affine and Permutation Orbifolds
Victor G. Kac, Roberto Longo, Feng Xu
We consider properties of solitons in general orbifolds in the algebraic quantum field theory framework and constructions of solitons in affine and permutation orbifolds. Under gen…

Topological Sectors and a Dichotomy in Conformal Field Theory
Roberto Longo, Feng Xu
Let A be a local conformal net of factors on the circle with the split property. We provide a topological construction of soliton representations of the tensor product of n copies…

Strong additivity and conformal nets
Feng Xu
We show that the fixed point subnet of a strongly additive conformal net under the action of a compact group is strongly additive. Using the idea of the proof we define the notion…
