摘要：
Several expressions for quantum entropy proposed in the literature are evaluated within the Weyl-Wigner-Moyal phase-space representation of quantum mechanics, with emphasis on some important subtle points in this approach. It has been found that the Renyi-Sussmann entropy and its linearization are distinguished because of their properties.
