    "abstract": "In a recent paper [PRE 62, 4665 (2000)] (quant-ph/0203102) Manfredi and Feix\nproposed an alternative definition of quantum entropy based on Wigner\nphase-space distribution functions and discussed its properties. They proposed\nalso some simple rules to construct positive-definite Wigner functions which\nare crucial in their discussion. We show, however, that the main results\nobtained and their discussion are incorrect.",
