Mirror extensions of local nets
Feng Xu
In this paper we prove a general theorem on the extensions of local nets which was inspired by recent examples of exotic extensions for Virasoro nets with central charge less than…
Conformal Nets Associated with Lattices and Their Orbifolds
Chongying Dong, Feng Xu
In this paper we study representations of conformal nets associated with positive definite even lattices and their orbifolds with respect to isometries of the lattices. Using previ…
Intersections of finite families of finite index subfactors
Vaughan F. R. Jones, Feng Xu
We prove that finiteness of the index of the intersection of a finite set of finite index subalgebras in a von Neumann algebra (with small centre) is equivalent to the finite dimen…
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…
3-manifold invariants from cosets
Feng Xu
We construct unitary modular categories for a general class of coset conformal field theories based on our previous study of these theories in the algebraic quantum field theory fr…
On a Conjecture of Kac-Wakimoto
Feng Xu
We prove a conjecture about mininmal index of certain representations of Coset Algebraic Conformal Field Theories under general conditions as formulated previously by us. As a by-p…
