A bstract In this work we present an alternative method to construct diverse non-relativistic
Chern-Simons supergravity theories in three spacetime dimensions. To this end, we apply …

By means of the Lie algebra expansion method, the centrally extended conformal algebra in
two dimensions and the bms _ 3 bms 3 algebra are obtained from the Virasoro algebra. We …

The coupling of spin-3 gauge fields to three-dimensional Maxwell and AdS-Lorentz gravity
theories is presented. After showing how the usual spin-3 extensions of the AdS and the …

A bstract In the present work we find novel Newtonian gravity models in three space-time
dimensions. We first present a Maxwellian version of the extended Newtonian gravity, which …

In this work we obtain known and new supersymmetric extensions of diverse asymptotic
symmetries defined in three spacetime dimensions by considering the semigroup expansion …

We explore N= 1 supersymmetric extensions of algebras going beyond the Poincaré and
AdS ones in three spacetime dimensions. Besides reproducing two known examples, we …

In this article we describe the Java library that we have recently constructed to automatize
the S-expansion method, a powerful mathematical technique allowing to relate different Lie …

We investigate the number of distinct resonant algebras depending on the generator
content, which consists of the Lorentz generator, translation, and new additional Lorentz-like …

By means of the Lie algebra expansion method, the centrally extended conformal algebra in
two dimensions and the $\mathfrak {bms} _ {3} $ algebra are obtained from the Virasoro …
