Scientific paper

The author presents a general method to detect and analyse the structure within galaxy systems. The method does not need any hint about the number, richness, shape or any other feature of the structures it is looking for. Basically the method is obtained from the multivariate extension of a non-parametric clustering analysis presented by Pisani (1994). In this work he assumes that the presence of dynamical structure is indicated by significant fluctuations in the distribution of integrated physical parameters. He presents here the results obtained for two well known clusters: Coma and Cancer. Both these clusters show substructure.
