The persistence properties of the T=0 coarsening dynamics of one-dimensional q-state Potts model was studied. A modified mean-field approximation (MMFA) was used for the study purpose. In the approximation, the correct time dependence of the mean density of persistent spins was imposed while the spatial correlations between the interfaces separating spins with different Potts states was ignored.
