Abstract
<jats:p>We develop a geometric and operationally explicit construction of correspondence rules (Bopp operators) for s-parametrized Stratonovich–Weyl phase-space symbols associated with symmetric irreducible representations of SU(d). Our main result is an intertwining procedure showing that all s-ordered Bopp operators are generated from the Husimi rules by applying continuous powers of the intertwining operator Υλ(L2). This is illustrated with the cases of SU(2) and SU(3). We show that, unlike the SU(2) case where the rules reduce to first-order vector fields, higher-rank SU(d) systems exhibit genuine higher-order differential contributions. This approach avoids cumbersome group-theoretical calculations, gives a transparent geometric interpretation of the phase-space map, and extends and complements results beyond spin systems.</jats:p>
