1. Extended noncommutative Minkowski spacetimes and hybrid gauge symmetries / Ballesteros, Angel ; Mercati, Flavio
We study the Lie bialgebra structures that can be built on the one-dimensional central extension of the Poincaré and (A)dS algebras in (1 + 1) dimensions. [...]

2. Noncommutative Relativistic Spacetimes and Worldlines from 2 + 1 Quantum (Anti-)de Sitter Groups / Herranz, Francisco J. ; Ballesteros, Ángel ; Bruno, N. Rossano
The κ -deformation of the (2 + 1)D anti-de Sitter, Poincaré, and de Sitter groups is presented through a unified approach in which the curvature of the spacetime (or the cosmological constant) is considered as an explicit parameter. [...]

3. The κ -(A)dS quantum algebra in (3 + 1) dimensions / Ballesteros, Ángel ; Herranz, Francisco J. ; Musso, Fabio ; Naranjo, Pedro
The quantum duality principle is used to obtain explicitly the Poisson analogue of the κ -(A)dS quantum algebra in ( 3+1 ) dimensions as the corresponding Poisson–Lie structure on the dual solvable Lie group. [...]

4. Towards ( 3+1 ) gravity through Drinfel'd doubles with cosmological constant / Ballesteros, Angel ; Herranz, Francisco J. ; Naranjo, Pedro
We present the generalisation to ( 3+1 ) dimensions of a quantum deformation of the ( 2+1 ) (Anti)-de Sitter and Poincaré Lie algebras that is compatible with the conditions imposed by the Chern–Simons formulation of ( 2+1 ) gravity. [...]

5. A ( 2+1 ) non-commutative Drinfel'd double spacetime with cosmological constant / Ballesteros, Angel ; Herranz, Francisco J. ; Meusburger, Catherine
We show that the Drinfel'd double associated to the standard quantum deformation slη(2,R) is isomorphic to the (2+1) -dimensional AdS algebra with the initial deformation parameter η related to the cosmological constant Λ=η2 . [...]
