The aim of this study is to search for quasi-periodical structures at moderate cosmological redshifts z ≲ 0.5. We mainly use the SDSS DR7 data on luminous red galaxies (LRGs) with 0.16 ≤ 0.47. At first, we analyze features (peaks) in power spectra radial (shell-like) distributions using separate angular sectors sky and calculate within each sector. As a result, found some signs large-scale anis...

The construction of continuous shearlet transform has been extended to higher dimensions. It was generalized a group that is topologically isomorphic semidirect product locally compact groups. In this paper, by unified theoretical linear algebra approach the representation theory, class transforms obtained from quasi-regular presented. order develop such representation, we utilize homogeneous s...
