Abstract
Observational relations are derived in an inhomogeneous cosmological model consisting of three regions: the inner low-density homogeneous region, the self-similar inhomogeneous region, and the outer, nearly flat homogeneous region. The boundary between the inner region and the self-similar region is assumed to be in a spherical shell corresponding to the epoch of redshift z = 1.5-2.0, when the numbers of quasars and Lyα clouds changed rapidly. The observational significance of the comparatively large matter density in the self-similar region is discussed in connection with various cosmological observations such as the angular diameter, the number density per unit redshift, and the number count of galaxies.
