Bicrossproduct vs. twist quantum symmetries in noncommutative geometries: the case of $\varrho$-Minkowski

Giuseppe Fabiano, Giulia Gubitosi, Fedele Lizzi +2

We discuss the quantum Poincaré symmetries of the $\varrho$-Minkowski spacetime, a space characterised by an angular form of noncommutativity. We show that it is possible to give t…
