RT info:eu-repo/semantics/article T1 The κ-(A)dS quantum algebra in (3+1) dimensions A1 Ballesteros Castañeda, Ángel A1 Herranz Zorrilla, Francisco José A1 Musso, Fabio A1 Naranjo, Pedro K1 Anti-de Sitter K1 Cosmological constant K1 Quantum groups K1 Poisson–Lie groups K1 Lie bialgebras K1 Quantum duality principle K1 Physics K1 Física AB 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. The construction is fully performed in a kinematical basis and deformed Casimir functions are also explicitly obtained. The cosmological constant is included as a Poisson–Lie group contraction parameter, and the limit →0leads to the well-known κ-Poincaré algebra in the bicrossproduct basis. A twisted version with Drinfel’d double structure of this κ-(A)dS deformation is sketched.
