"Double-trace" Deformations, Boundary Conditions and Spacetime Singularities
read the original abstract
Double-trace deformations of the AdS/CFT duality result in a new perturbation expansion for string theory, based on a non-local worldsheet. We discuss some aspects of the deformation in the low energy gravity approximation, where it appears as a change in the boundary condition of fields. We relate unique features of the boundary of AdS to the worldsheet becoming non-local, and conjecture that non-local worldsheet actions may be generic in other classes of backgrounds.

When AdS$_3$ Grows Hair: Boson Stars, Black Holes, and Double-Trace Deformations

Neumann scalars in AdS: partition functions and phases
Neumann scalars in AdS admit one-loop partition functions obtained by contour deformation from the Dirichlet result; the stricter unitarity bound then yields qualitatively different phase diagrams that are corroborate...

Neumann scalars in AdS: partition functions and phases
Neumann-boundary scalars in AdS_{2..5} get one-loop phase diagrams that are much more restricted than the Dirichlet ones, and symmetry breaking is often blocked by unitarity and thermal-series convergence constraints.
