Nonlinear effects and coarse-graining in general relativity
I will discuss the nonlinear effects of general relativity which appear if we perform the coarse-graining of the gravitational field and its sources over the fine details of the solution. In particular I will focus on effects of many compact sources of gravitational field and the case of nested inhomogeneities extending over many scales.
