Abstract
The renormalization group method has been adapted to the analysis of t he long-time behavior of the nonlinear partial differential equation a nd has demonstrated its power in the study of critical phenomena of gr avitational collapse. In the present work we apply the renormalization group to the Einstein equation in cosmology and carry out a detailed analysis of renormalization group flow in the vicinity of the scale in variant fixed point in the spherically symmetric and inhomogeneous dus t filled universe model.
