Correspondence rules for Wigner functions over $SU\left(3\right)/U\left(2\right)$

We present results on the product for Wigner functions over . In particular, we present a form of the so-called correspondence rules, which provide a differential form of the product and when is an generator. For the Wigner map, these rules must contain second order derivatives and thus substantially differ from the rules of other known cases. (paper)
