Phase spaces of Doubly Special Relativity
arXiv:hep-th/0312045 · doi:10.1016/j.physletb.2003.12.035
Abstract
We show that depending on the direction of deformation of $κ$-Poincaré algebra (time-like, space-like, or light-like) the associated phase spaces of single particle in Doubly Special Relativity theories have the energy-momentum spaces of the form of de Sitter, anti-de Sitter, and flat space, respectively.
