Snyder-de Sitter model from two-time physics
arXiv:1010.6258 · doi:10.1103/PhysRevD.82.105031
Abstract
We show that the symplectic structure of the Snyder model on a de Sitter background can be derived from two-time physics in seven dimensions and propose a Hamiltonian for a free particle consistent with the symmetries of the model.
