"Twisted Covariance and DFR Spacetime Quantisation"

We will discuss a class of models of quantum spacetime. In particular
we will show that the approach to covariance in terms of coproducts
twisted a` la Drin'feld is equivalent to the DFR product with an additional
non invariant constrain. Indeed, the tensor character of the commutator
of the quantum coordinates cannot be suppressed even in the formalism
of twisted covariance.
