Abstract
Using general but simple covariance arguments, we classify the 'quantu m' Minkowski spaces for dimensionless deformation parameters. This req uires a previous analysis of the associated Lorentz groups, which repr oduces a previous classification by Woronowicz and Zakrzewski. As a co nsequence of the unified analysis presented, we give the commutation p roperties, the deformed (and central) length element and the metric te nsor for the different spacetime algebras.
