Query: Localizability in $\kappa$-Minkowski Spacetime   Using the methods of ordinary quantum mechanics we study $\kappa$-Minkowski
space as a quantum space described by noncommuting self-adjoint operators,
following and enlarging arXiv:1811.08409. We see how the role of Fourier
transforms is played in this case by Mellin transforms. We briefly discuss the
role of transformations and observers.
