Title: Analysis of the large-scale structure of the Universe
Abstract: A method of calculation of the large-scale structure of the Universe based on the adiabatic theory (A-theory) of its formation is proposed. The initial spectrum of perturbation is related to some observable parameters of the structure, which are objectively defined as a set of regions enclosed by the border of constant density ρ = ρc (ρc is a free parameter of the theory). The parameters are: (1) W is the fraction of matter within the regions of high density ρ > ρc; (2) L is the mean size of a region defined as the diameter of the circle circumscribed around the region; (3) D is a mean separation of dense regions taken along a straight line and (4) n is a mean number of dense regions in a unit area.
