Query: Fluctuations in galaxy counts: a new test for homogeneity versus
  fractality   Fractal properties are usually characterized by means of various statistical
tools which deal with spatial average quantities. Here we focus on the
determination of fluctuations around the average counts and we develop a test
for the study of galaxy distribution both in redshift and magnitude space.
Fluctuations in the counts of galaxies, in a fractal distribution, are of the
same order of the average number at all scales as a function of redshift and
magnitude. We point out that the study of these kind of fluctuations can be a
powerful test to understand the nature of galaxy clustering at very large
scales.
