    "abstract": "We study analytically the ground-state stability of a Bose-Einstein\ncondensate (BEC) confined in an harmonic trap with repulsive or attractive\nzero-range interaction by minimizing the energy functional of the system. In\nthe case of repulsive interaction the BEC mean radius grows by increasing the\nnumber of bosons, instead in the case of attractive interaction the BEC mean\nradius decreases by increasing the number of bosons: to zero if the system is\none-dimensional and to a minimum radius, with a maximum number of bosons, if\nthe system is three-dimensional.",
