Abstract
Results are reported on N-body simulations of the large-scale structure of the Universe starting from non-Gaussian initial conditions in a cold dark matter cosmogony. Three multiplicative models are condidered where the peculiar gravitational potential is obtained by performing a non-linear transformation on a Gaussian random field: while keeping the standard form for the initial power spectrum, this procedure provides highly non-random phases. The resulting distributions in space and velocity are analysed by different statistical tests and compared with the evolution of a standard Gaussian model with the same initial amplitude.
