Canonical representation of the Snyder-de Sitter algebra with correct flat and commutative limits
V. G. Kupriyanov, E. L. F. de Lima
The Snyder--de Sitter algebra provides a Lorentz-covariant deformation of phase-space geometry characterized by a curvature parameter and a noncommutativity parameter . We c…

Symplectic realization of generalized Snyder-Poisson algebra
V. G. Kupriyanov, E. L. F. de Lima
We investigate Snyder space-time and its generalizations, including Yang and Snyder-de-Sitter spaces, which constitute manifestly Lorenz invariant noncommutative geometries. This w…
