Cosmological Redshift-Space Distortion II: distance in an inhomogeneous universe and evolution of bias

We discuss the two potentially important effects which should be taken into account in the analysis of the cosmological redshift-space distortion especially at high redshifts; the effect of inhomogeneities in the light propagation and the evolution of bias. Although such inhomogeneities affect significantly the degree of the cosmological redshift distortion, one can determine the density parameter $\Omega_0$ from the distortion pattern at $z=0$, and the cosmological constant $\lambda_0$ from that at $z = (1\sim 2)$. In particular we show that in low-density ($\Omega_0\ll 1$) universes one can determine the value of $\lambda_0$ and even the evolution of the bias parameter almost insensitively to the degree of the clumpiness of the matter distribution in the universe.
