• Given a conformal QFT local net of von Neumann algebras $${\mathcal {B}_2}$$ on the two-dimensional Minkowski spacetime with irreducible subnet $${\mathcal {A} \otimes \mathcal {A}}$$, where $${\mathcal {A}}$$ is a completely rational net on the left/right light-ray, we show how to consistently add a boundary to $${\mathcal {B}_2}$$: we provide a procedure to construct a Boundary CFT net $${\mathcal {B}}$$ of von Neumann algebras on the half-plane x >  0, associated with $${\mathcal {A}}$$, and… CONTINUE READING
