Comment on "Equivalence between SWH phase operator and Ban's phase operator revealed by virtue of the vertical bar eta > representation'' by Hong-yi Fan and Hui Zou

Fan and Zou [Phys. Lett. A 255 (1999) 7; 258 (1999) 74] prove and disprove
the 'identity' between the phase operator of Shapiro, Wagner and Hradil and
that of Ban. The 'nonequivalence' would be misreading by results of Hradil
[Phys. Rev. A 47 (1993) 2376] and Ban [Phys. Rev. A 50 (1991) 2785]. (C) 2
