We use a change of variables that turns the critical nonlinear Schrodinger equation into the critical nonlinear Schrodinger equation with isotropic harmonic potential, in any spare dimension. This change of variables is isometric on L-2, and bijective on some time intervals. Using the known results for the critical nonlinear Schrodinger equation, this provides information for the properties of Bose-Einstein condensate in spare dimension one and two. We discuss in particular the wave collapse phenomenon.
