Abstract
A general stability criterion is derived for the ground states of the Gross -Pitaevskii equation, which describes attractive Bose-Einstein condensates confined in a magnetic trap. These ground states are shown to avoid the col lapse in finite time and are proven to be stable in two and three spatial d imensions.
