Ballesteros Castañeda, Ángel Gutiérrez Sagredo, Iván Herranz Zorrilla, Francisco José Meusburger, Catherine . Naranjo, Pedro 2017-08 8th International Workshop DICE2016: Spacetime - Matter - Quantum Mechanics 12–16 September 2016, Castiglioncello, Italy Noncommutative spacetimes are widely believed to model some properties of the quantum structure of spacetime at the Planck regime. In this contribution the construction of (anti-)de Sitter noncommutative spacetimes obtained through quantum groups is reviewed. In this approach the quantum deformation parameter z is related to a Planck scale, and the cosmological constant Λ plays the role of a second deformation parameter of geometric nature, whose limit Λ → 0 provides the corresponding noncommutative Minkowski spacetimes. application/pdf http://hdl.handle.net/10259/4721 eng IOP Publising Quantum groups and noncommutative spacetimes with cosmological constant info:eu-repo/semantics/article TEXT RIUBU.
