00925njm 22002777a 4500 dc Ballesteros Castañeda, Ángel author Gutiérrez Sagredo, I. author Herranz, F.J. author Meusburger, Catherine author Naranjo, Pedro author 2017 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 Lambda plays the role of a second deformation parameter of geometric nature, whose limit Lambda → 0 provides the corresponding noncommutative Minkowski spacetimes.
