Einstein manifolds with torsion and nonmetricity
Dietmar Silke Klemm, Lucrezia Ravera
Manifolds endowed with torsion and nonmetricity are interesting both from the physical and the mathematical points of view. In this paper, we generalize some results presented in t…
On the supersymmetry invariance of flat supergravity with boundary
Patrick Concha, Lucrezia Ravera, Evelyn Rodríguez
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 boun…
Generalized cosmological term in D=4 supergravity from a new AdS-Lorentz superalgebra
Diego M. Peñafiel, Lucrezia Ravera
A new supersymmetrization of the so-called AdS-Lorentz algebra is presented. It involves two fermionic generators and is obtained by performing an abelian semigroup expansion of th…
Generalized AdS-Lorentz deformed supergravity on a manifold with boundary
A. Banaudi, L. Ravera
The purpose of this paper is to explore the supersymmetry invariance of a particular supergravity theory, which we refer to as D=4 generalized AdS-Lorentz deformed supergravity, in…
Group Theoretical Hidden Structure of Supergravity Theories in Higher Dimensions
L. Ravera
The purpose of my PhD thesis is to investigate different group theoretical and geometrical aspects of supergravity theories. To this aim, several research topics are explored: On o…
Hidden Role of Maxwell Superalgebras in the Free Differential Algebras of D=4 and D=11 Supergravity
L. Ravera
The purpose of this paper is to show that the so-called Maxwell superalgebra in four dimensions, which naturally involves the presence of a nilpotent fermionic generator, can be in…
