On the Maxwell supergravity and flat limit in 2+1 dimensions
Patrick Concha, Diego M. Peñafiel, Evelyn Rodríguez
The construction of the three-dimensional Chern-Simons supergravity theory invariant under the minimal Maxwell superalgebra is presented. We obtain a supergravity action without co…

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…
