Abstract
A family of states built from the uncertainty principle on the fuzzy sphere has been shown to reproduce the stereographic projection in the large limit. These generalized squeezed states are used to construct an associative star product which involves a finite number of derivatives on its primary functional space. It is written in terms of a variable on the complex plane. We show that it actually coincides with the one found by Gross and Presnajder in the simplest cases, endowing the later with a supplementary physical interpretation. We also show how the spherical harmonics emerge in this setting.
