Supergravity at the boundary of AdS supergravity [PDF]
, 2009 We give a general analysis of AdS boundary conditions for spin-3/2 Rarita-Schwinger fields and investigate boundary conditions preserving supersymmetry for a graviton multiplet in AdS_4.

Extremal Black Holes in Supergravity and the Bekenstein-Hawking Entropy
Entropy, 2002 : We review some results on the connection among supergravity central charges, BPS states and Bekenstein-Hawking entropy. In particular, N = 2 super-gravity in four dimensions is studied in detail.

On the supersymmetry invariance of flat supergravity with boundary [PDF]
Journal of High Energy Physics, 2019 The supersymmetry invariance of flat supergravity (i.e., supergravity in the absence of any internal scale in the Lagrangian) in four dimensions on a manifold with non-trivial boundary is explored.

Higher-derivative supergravity, AdS4 holography, and black holes [PDF]
Journal of High Energy Physics, 2021 We use conformal supergravity techniques to study four-derivative corrections in four-dimensional gauged supergravity. We show that the four-derivative Lagrangian for the propagating degrees of freedom of the N\documentclass[12pt]{minimal} \usepackage ...

The Large-N Limit of Superconformal Field Theories and Supergravity [PDF]
, 1997 We show that the large-N limits of certainconformal field theories in various dimensions includein their Hilbert space a sector describing supergravityon the product of anti-de Sitter spacetimes, spheres, and other compact manifolds.
