2018-02-01T11:55:04Z urn:hdl:10259/4721 Quantum groups and noncommutative spacetimes with cosmological constant Ballesteros Castañeda, Ángel Gutiérrez Sagredo, Iván Herranz Zorrilla, Francisco José Meusburger, Catherine . Naranjo, Pedro 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. 2018-02-01T11:55:04Z 2018-02-01T11:55:04Z 2017-08 info:eu-repo/semantics/article 1742-6588 http://hdl.handle.net/10259/4721 10.1088/1742-6596/880/1/012023 eng Journal of Physics: Conference Series. 2017, V. 880, n. 1, 012023 https://doi.org/10.1088/1742-6596/880/1/012023 info:eu-repo/grantAgreement/MINECO/MTM2013-43820-P info:eu-repo/grantAgreement/MINECO/MTM2016-79639-P info:eu-repo/grantAgreement/JCyL/BU278U14 info:eu-repo/grantAgreement/JCyL/VA057U16 info:eu-repo/grantAgreement/UE/COST-MP1405 https://creativecommons.org/licenses/by/3.0/ info:eu-repo/semantics/openAccess Attribution 3.0 Unported IOP Publising
