Abstract
It was shown that the ground states obtained by the projection on
the states of the lowest Landau level are unstable due to the formation of
the isolated vortex decreasing the energy at the partial Ll fillings.This
statement is valid due to the different dependence on the sample size of the various terms in the free energy
like the free energy of the rotating liquid irrelevant to the details of
the microscopical structure and the interaction.
