Quantum groups and noncommutative spacetimes with cosmological constant
A. Ballesteros, I. Gutiérrez-Sagredo, F. J. Herranz +2
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-)d…
On Hamiltonians with position-dependent mass from Kaluza-Klein compactifications
Ángel Ballesteros, Iván Gutiérrez-Sagredo, Pedro Naranjo
In a recent paper (J.R. Morris, Quant. Stud. Math. Found. 2 (2015) 359), an inhomogeneous compactification of the extra dimension of a five-dimensional Kaluza-Klein metric has been…
A universal non-quasitriangular quantization of the Heisenberg group
A. Ballesteros, Enrico Celeghini, F. J. Herranz +2
A universal R--matrix for the quantum Heisenberg algebra h(1)q is presented. Despite of the non--quasitriangularity of this Hopf algebra, the quantum group induced from it coincide…
4D Quantum Affine Algebras and Space--Time q-Symmetries
A. Ballesteros, F. J. Herranz, M. A. del Olmo +1
A global model of -deformation for the quasi--orthogonal Lie algebras generating the groups of motions of the four--dimensional affine Cayley--Klein geometries is obtained start…
