By using the local density approximation, Bose-Einstein condensation of Bose gas in the low dimensional space is investigated. The results show that when a proper external potential is taken, BEC may occur in the low dimensional space. The critical temperature Tc, the ground state fraction N0/N and the behaviour (jump or not) of the heat capacity C depend on the shape of the potential.

The discussion is made on the relation between the state density of systems and the dimensionality of Bose-Einstein Condensation(BEC),with the further stress laid on the analysis of low dimensional BEC under the influence of power-law potential and harmonic potential.The result is the non-production of low dimensional BEC with no external potential and the production of one-dimensional and two-dimensional BEC under the power of external potential.
