Holographic identification of the candidate boundary CFT

Establish a holographic identification of the free abelian boundary CFT constructed from the constant non-Riemannian DFT vielbeins with the bulk non-Riemannian holographic system.

Background

The supplemental material constructs a free abelian boundary model whose propagating sector is a free N=(1,1) scalar multiplet with two chiral fermions. Multiple copies can provide the torus seed associated with symmetric-product CFTs, and the model realizes two Witt algebras and supersupersymmetry.

Although this theory has the required classical symmetry structure, the paper does not establish that it is the holographic dual of the bulk construction. The relation between the candidate boundary CFT and the proposed non-Riemannian holographic saddles remains unresolved.

References

A holographic identification of this classical boundary CFT remains open.
