Cosmological simulations: a tool for understanding the formation of
  large scale structure and connection with the Newtonian cosmology
  In this work we study the cosmological simulations as a tool to understand
the formation of large-scale structure of the universe, for this, we show the
equivalence of Newtonian cosmology with Poisson gauge and we study the solution
of the Einstein's field equations for this gauge. The simulations are essential
for taking account the results of the cosmological model, allowing to compare
the results with observational data. The N-bodies simulations have been used
from systems of few bodies to the evolution and formation of nonlinear large
scale structure as filaments and galactic halos.
