Description/Abstract
We show how the interplay of non–linear dynamics, self–gravity, and fluctuations leads to self–affine behavior of matter density correlations quite generically, i.e., with a power law exponent whose value does not depend in a very direct way on the specific details of the dynamics. This we do by means of the Renormalization Group, a powerful analytical tool for extracting asymptotic behavior of many-body systems.
