Combined an end-of-the-world brane with a finite holographic cutoff and derived the corresponding lower-dimensional brane-world description by partial reduction.

Abstract

The paper studies AdS gravity with both an end-of-the-world boundary and a finite cutoff boundary. Partial reduction produces a brane-world gravity description coupled to a TT̄-deformed field theory.

Context

End-of-the-world branes describe boundaries or gravitational sectors, while holographic TT̄ deformation introduces a finite radial cutoff. Their simultaneous presence requires a common geometric treatment.

Main result

Using partial reduction, the work relates the cutoff AdS construction to a lower-dimensional gravitational theory glued to a TT̄-deformed field theory.

Why it matters

The construction supplies a controlled setting in which boundary gravity and finite-cutoff holography can be studied together.
