| Abstract: | A two-dimensional Gross-Pitaevskii equation describing Bose-Einstein condensation in an axial symmetry non-harmonic trap is solved.Converged wave functions,chemical potentials,and internal energies in Bose-Einstein condensation are obtained.Ground-state of Bose-Einstein condensation with atomic interaction is investigated.A comparison between harmonic and non-harmonic traps is reported. |

| Keywords: | Bose-Einstein condensation Gross-Pitaevskii equation non-harmonic trap |
