摘要：

Multiplicative Gaussian white noise is included in the nonlinear Schrodinger equation of one and two dimensions in the critical case, in which collapse occurs. The collective coordinate method is used to derive analytical results concerning the effects of the noise on the collapse process. This approach makes it possible to distinguish between the one- and two-dimensional case. The analytical results are in good agreement with numerical results obtained directly from the partial differential equation.
