Abstract

We prove that the Podleś spheres S²_q converge in quantum Gromov–Hausdorff distance to the classical 2-sphere as the deformation parameter q tends to 1. Moreover, we construct a q-deformed analogue of the fuzzy spheres, and prove that they converge to S²_q as their linear dimension tends to infinity, thus providing a quantum counterpart to a classical result of Rieffel.
