Abstract
The galaxy and cluster distribution, as revealed by the observational data, displays a rich variety of nonlinear structures, such as filaments, walls, and a hierarchical organization at small scales. Here we discuss the results of different N-body numerical simulations which indicate that a fractal matter distribution at scales below 4-7 h-s Mpc should be the natural outcome of the nonlinear evolution of a self-gravitating collisionless fluid in the Hubble flow. This is one of the few examples where an observed fractal distribution in physical space is dynamically related to the system evolution. We finally discuss the stability properties of the dynamically evolved fractal point distribution.
