We give a general review of extended supergravities and their gauging using the duality-
covariant embedding tensor formalism. Although the focus is on four-dimensional theories …

A bstract Spherical black hole (BH) solutions in Einstein-Maxwell-scalar (EMS) models
wherein the scalar field is non-minimally coupled to the Maxwell invariant by some coupling …

A bstract Motivated by its well defined higher dimensional origin, a detailed study of D=
4\(\mathcal {N}= 8\) supergravity with a dyonically gauged\(\mathrm {I}\mathrm {S}\mathrm …

A bstract We identify the space of symplectic deformations of maximal gauged supergravity
theories. Coordinates of such space parametrize inequivalent supergravity models with the …

A bstract Multi-parametric families of AdS 4 vacua with various amounts of supersymmetry
and residual gauge symmetry are found in the [SO (1, 1)× SO (6)]⋉ ℝ 12 maximal …

A bstract We perform a systematic search for anti-de Sitter vacua of maximal supergravity
with\(\mathcal {N}> 2\) residual supersymmetries. We find that maximal supergravity admits …

A bstract Type IIB S-folds of the form AdS 4× S 1× S 5 are conjectured to correspond to new
strongly coupled three-dimensional CFT's on a localised interface of SYM 4. In this work we …

A bstract We construct concrete counterterms of the Balasubramanian-Kraus type for
Einstein-scalar theories with designer gravity boundary conditions in AdS 4, so that the total …

We present a variational formulation of Einstein–Maxwell-dilaton theory in flat spacetime,
when the asymptotic value of the scalar field is not fixed. We obtain the boundary terms that …

A bstract In this article we study a family of four-dimensional,\(\mathcal {N}\)= 2 supergravity
theories that interpolates between all the single dilaton truncations of the SO (8) …
