Spin Structures and AdS Holography
Nikolay Bobev, Pieter Bomans
We study the importance of spin structures as defining data for 11d supergravity backgrounds of the form AdS with a free orbifold action. For a generic c…
AdS Holography and Higher-Derivative Supergravity
Nikolay Bobev, Kiril Hristov, Valentin Reys
We study four-derivative corrections to 5d minimal gauged supergravity using tools from conformal supergravity. There are two supersymmetric invariants at the four-…
Holographic 3d Conformal Manifolds
Nikolay Bobev, Fridrik Freyr Gautason, Jesse van Muiden
We construct and study several examples of continuous families of AdS solutions of four-dimensional maximal gauged supergravity. These backgrounds provide the…
Higher-Derivative Supergravity, AdS Holography, and Black Holes
Nikolay Bobev, Anthony M. Charles, Kiril Hristov +1
We use conformal supergravity techniques to study four-derivative corrections in four-dimensional gauged supergravity. We show that the four-derivative Lagrangian for the propagati…
The Holographic Conformal Manifold of 3d -fold SCFTs
Nikolay Bobev, Fridrik Freyr Gautason, Jesse van Muiden
We employ a non-compact gauging of four-dimensional maximal supergravity to construct a two-parameter family of AdS J-fold solutions preserving supersymmetry. A…
Marginal deformations from type IIA supergravity
Nikolay Bobev, Pieter Bomans, Fridrik Freyr Gautason +1
We study marginal deformations of a class of three-dimensional SCFTs that admit a holographic dual description in massive type IIA supergravity. We compute the dime…
