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. eng https://creativecommons.org/licenses/by/3.0/ info:eu-repo/semantics/openAccess Attribution 3.0 Unported Quantum groups and noncommutative spacetimes with cosmological constant info:eu-repo/semantics/article
