Nonuniqueness of Kivelson, Kallin, Arovas and Schrieffer' fractional charge

It is found that the magnetic length has not been treated correctly to calculate the classical action. In fact, the charge and the magnetic length have not been resolved. It is of serious consequences because fractional charge completely disappears and only the flux area, $\l_o^2$ becomes fractional. The results of Kivelson et al are therefore not unique.
