Scaling behaviour in the truncated Zel'dovich approximation.

We analyse the scaling properties of the matter distribution generated by the truncated Zel'dovich approximation (TZA) for a universe dominated by a mixture of cold+hot non-baryonic dark matter. At the present epoch, the dark-matter distribution generated by TZA displays an intermediate scaling behaviour between about 4 and 60 h Mpc with a correlation dimension D ∼2 for q≥2. The possible implications of these results are considered. [ABSTRACT FROM AUTHOR]
