Comment on "Can we measure structures to a precision better than the Planck length?"[arXiv:1205.3636], by Sabine Hossenfelder
Sergio Doplicher, Gherardo Piacitelli, Luca Tomassini +1
First principles do imply a non-zero minimal distance between events in spacetime, but no positive lower bound to the precision of the measurement of a single coordinate.

Canonical k-Minkowski Spacetime
Ludwik Dabrowski, Gherardo Piacitelli
A complete classification of the regular representations of the relations [T,X_j] = (i/k)X_j, j=1,...,d, is given. The quantisation of RxR^d canonically (in the sense of Weyl) asso…

Quantum Spacetime: a Disambiguation
Gherardo Piacitelli
We review an approach to non-commutative geometry, where models are constructed by quantisation of the coordinates. In particular we focus on the full DFR model and its irreducible…
