Scalar perturbations in f(R) cosmologies in the late Universe
Standard approach in cosmology is hydrodynamical approach, when galaxies are smoothed distributions of matter. Then we model the Universe as a fluid. But we know, that the Universe has a discrete structure on scales 150 - 370 MPc. Therefore we must use the generalized mechanical approach, when is the mass concentrated in points. Methods of computations are then different. We focus on -theories of gravity and we work in the cell of uniformity in the late Universe. We do the scalar perturbations...
