We describe, in an algebraic way, the κ-deformed extended Snyder models, that depend on three parameters β, κ and λ, which in a suitable algebra basis are described by the de Sitter algebras o(1, N). The commutation relations ...

We introduce the perturbative ℏ-power series (ℏ - Planck constant) providing the algebraic solutions of D=4 quantum Snyder and Yang models which describe relativistic quantum space-times and Lorentz-covariant quantum phase ...
