The κ-(A)dS quantum algebra in (3+1) dimensions Ballesteros Castañeda, Ángel Herranz Zorrilla, Francisco José Musso, Fabio Naranjo, Pedro Anti-de Sitter Cosmological constant Quantum groups Poisson–Lie groups Lie bialgebras Quantum duality principle Physics Física 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.
