The recent availability of
dimensional samples of galaxies and clusters permits a
study of their spatial properties. We present a brief
of galaxy correlations based on the methods modern
Physics. These methods which able to identify
and non-analytical prop ties, allow us to test the
homogeneity assumption of luminous matter distribution.
We conclude that both the three dimensional prop ties,
angular log <I>N </I>- log S relation, point out the
fact that the
distribution of galaxies and clusters fractal with

This result has important implications for the
framework that should be adopted.
