Distribution of Galaxies : Scaling vs Fractality
نویسنده
چکیده
A synthesis of the observational data on the distribution of galaxies is made by expressing the statistical counts in cells of variable size in terms of the generating functional for the N-point correlation functions. A complex fractal structure is thereby derived from a simple scaling property of the correlation functions and from the niteness of the overall density of galaxies. Bifractality occurs in two diierent scaling ranges. The formalism may be used to build new fractal structures for sets of points from scaling hypotheses on correlation functions.

Scaling of voids and fractality in the galaxy distribution
We study here, from first principles, what properties of voids are to be expected in a fractal point distribution and how the void distribution is related to its morphology. We show this relation in various examples and apply our results to the distribution of galaxies. If the distribution of galaxies forms a fractal set, then this property results in a number of scaling laws to be fulfilled by...
متن کاملA Study of Fractality and Long-Range Order in the Distribution of Transposable Elements in Eukaryotic Genomes Using the Scaling Properties of Block Entropy and Box-Counting
Repeats or Transposable Elements (TEs) are highly repeated sequence stretches, present in virtually all eukaryotic genomes. We explore the distribution of representative TEs from all major classes in entire chromosomes across various organisms. We employ two complementary approaches, the scaling of block entropy and box-counting. Both converge to the conclusion that well-developed fractality is...
متن کاملFractality and self-similarity in scale-free networks
Fractal scaling and self-similar connectivity behaviour of scale-free (SF) networks are reviewed and investigated in diverse aspects. We first recall an algorithm of box-covering that is useful and easy to implement in SF networks, the so-called random sequential box-covering. Next, to understand the origin of the fractal scaling, fractal networks are viewed as comprising of a skeleton and shor...
متن کاملScaling of quasibrittle fracture: hypotheses of invasive and lacunar fractality, their critique and Weibull connection
Considerable progress has been achieved in fractal characterization of the properties of crack surfaces in quasibrittle materials such as concrete, rock, ice, ceramics and composites. Recently, fractality of cracks or microcracks was proposed as the explanation of the observed size effect on the nominal strength of structures. This explanation, though, has rested merely on intuitive analogy and...
متن کاملScaling relations in dynamical evolution of star clusters
We have carried out a series of small scale collisional N-body calculations of single-mass star clusters to investigate the dependence of the lifetime of star clusters on their initial parameters. Our models move through an external galaxy potential with a logarithmic density profile and they are limited by a cut-off radius. In order to find scaling relations between the lifetime of star cluste...
