A bstract We show that the phase space of three-dimensional gravity contains two layers of
dualities: between diffeomorphisms and a notion of “dual diffeomorphisms” on the one hand …

In this work, we present the three-dimensional Maxwell Carroll gravity by considering the
ultra-relativistic limit of the Maxwell Chern-Simons gravity theory defined in three spacetime …

A bstract The stationary black hole solution of a Chern-Simons model based on the semi-
simple extension of the Poincaré gauge group is studied. The solution resembles the metric …

A bstract We extend a recent classification of three-dimensional spatially isotropic
homogeneous spacetimes to Chern-Simons theories as three-dimensional gravity theories …

A bstract In this paper, we present novel and known non-relativistic and ultra-relativistic spin-
3 algebras, by considering the Lie algebra expansion method. We start by applying the …

A bstract We continue analysis of [1] and study rigidity and stability of the\(\mathfrak
{b}\mathfrak {m}{\mathfrak {s}} _4\) algebra and its centrally extended version\(\widehat …

A bstract In this work we study a non-relativistic three dimensional Chern-Simons gravity
theory based on an enlargement of the Extended Bargmann algebra. A finite nonrelativistic …

Carroll symmetries arise when the velocity of light is sent to zero (ultra-relativistic limit). In
this paper, we present the construction of the three-dimensional Chern-Simons supergravity …

A bstract We show that an extended 3D Schrödinger algebra introduced in [1] can be
reformulated as a 3D Poincaré algebra extended with an SO (2) R-symmetry generator and …

A bstract We present a novel three-dimensional non-relativistic Chern-Simons supergravity
theory invariant under a Maxwellian extended Bargmann superalgebra. We first study the …
