$\kappa$-deformations of D=3 conformal versus deformations of D=4 AdS symmetries

J. Lukierski, V. D. Lyakhovsky, M. Mozrzymas

We describe the classical $o(3,2)$ $r$-matrices as generating the quantum deformations of either D=3 conformal algebra with mass-like deformation parameters or D=4 $AdS$ algebra wi…
