1. Curved momentum spaces from quantum (anti–)de Sitter groups in (3+1) dimensions / Ballesteros, A. ; Gubitosi, G. ; Gutierrez-Sagredo, I. ; Herranz, F. J.
Curved momentum spaces associated to the κ-deformation of the (3+1) de Sitter and anti–de Sitter algebras are constructed as orbits of suitable actions of the dual Poisson-Lie group associated to the κ-deformation with nonvanishing cosmological constant. [...]

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. Curved momentum spaces from quantum groups with cosmological constant / Ballesteros, Á. ; Gubitosi, G. ; Gutiérrez-Sagredo, I. ; Herranz, F.J.
We bring the concept that quantum symmetries describe theories with nontrivial momentum space properties one step further, looking at quantum symmetries of spacetime in presence of a nonvanishing cosmological constant Λ. [...]

4. 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. [...]

5. 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. [...]

6. 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 . [...]
