Holographic Dual of BCFT

Understand

We propose a holographic dual of a conformal field theory defined on a manifold with boundaries, i.e.

• boundary conformal field theory (BCFT).
• Our new holography, which may be called AdS/BCFT, successfully calculates the boundary entropy or g-function in two dimensional BCFTs and it agrees with the finite part of the holographic entanglement entropy.
• Moreover, we can naturally derive a holographic g-theorem.
