Abstract
We continue developing the freelance holography program, formulating gauge/gravity correspondence where the gravity side is formulated on a space bounded by a generic timelike codimension-one surface inside AdS and arbitrary boundary conditions are imposed on the gravity fields on the surface. Our analysis is performed within the Covariant Phase Space Formalism (CPSF). We discuss how a given boundary condition on the bulk fields on a generic boundary evolves as we move the boundary to another boundary inside AdS and work out how this evolution is encoded in deformations of the holographic boundary theory. Our analyses here extend the extensively studied T$\bar{\text{T}}$-deformation by relaxing the boundary conditions at asymptotic AdS or at the cutoff surface to be any arbitrary one (besides Dirichlet). We discuss some of the implications of our general freelance holography setting.

Reports on this Submission
Strengths
- The problem being considered in this paper is ambitious and very relevant.
- The explanations provided are clear.
- The proposal is illustrated with several examples.
Weaknesses
- The deformations are considered at the level of the classical bulk theory, so their holographic dual is restricted to the semiclassical EFT framework and does not have a separate field theory definition.
Report
I concur with the recommendation of the other referee that the paper be published in SciPost Physics Core.
