Open AccessHidden gauge structure of supersymmetric free differential algebras
The aim of this paper is to clarify the role of the nilpotent fermionic generator Q ′ introduced in [6] and appearing in the hidden supergroup underlying the free differential alge...

Open AccessN=1 and N=2 pure supergravities on a manifold with boundary
Working in the geometric approach, we construct the lagrangians of N = 1 and N = 2 pure supergravity in four dimensions with negative cosmological constant, in the presence of a non trivial boundary of space-time...

Open AccessOn extremal limits and duality orbits of stationary black holes
With reference to the effective three-dimensional description of stationary, single center solutions to (ungauged) symmetric supergravities, we complete a previous analysis on the definition of a general geome...

Extremal limits of rotating black holes
We consider non-extremal, stationary, axion-dilaton solutions to ungauged symmetric supergravity models, obtained by Harrison transformations of the non-extremal Kerr solution. We define a general algebraic pr...

On the Classification of Two Center Orbits for Magical Black Holes
We report on recent work [4] concerning the determination of the two-centered generic charge orbits of magical \(\mathcal{N} = 2\) and ...

Rotating black holes, global symmetry and first order formalism
In this paper we consider axisymmetric black holes in supergravity and address the general issue of defining a first order description for them. The natural setting where to formulate the problem is the De Don...

Short and Long SU(2, 2/4) Multiplets in the AdS/CFT Correspondence
We analyze short and long multiplets which appear in the OPE expansion of ‘chiral’ primary operators in N=4 Super Yang–Mills theory. Among them, higher spin long and new short multiplets appear having the inte...

‘Nonchiral’ Primary Superfields in the Add + 1/CFTd Correspondence
We consider some long multiplets describing bulk massive excitations of M-theory two-branes and IIB string three-branes which correspond to ‘nonchiral’ primary operators of the boundary OSp(8/4) and SU(2,2/4) ...
