Twisted (2+1) -AdS Algebra, Drinfel'd Doubles and Non-Commutative Spacetimes
Ángel Ballesteros, Francisco J. Herranz, Catherine Meusburger +1
We construct the full quantum algebra, the corresponding Poisson-Lie structure and the associated quantum spacetime for a family of quantum deformations of the isometry algebras of…
Generalised shear coordinates on the moduli spaces of three-dimensional spacetimes
Catherine Meusburger, Carlos Scarinci
We introduce coordinates on the moduli spaces of maximal globally hyperbolic constant curvature 3d spacetimes with cusped Cauchy surfaces S. They are derived from the parametrisati…
A (2+1) non-commutative Drinfel'd double spacetime with cosmological constant
Angel Ballesteros, Francisco J. Herranz, Catherine Meusburger
We show that the Drinfel'd double associated to the standard quantum deformation is isomorphic to the (2+1)-dimensional AdS algebra with the initial deformation paramet…
