We present a detailed comparison of the predictions of perturbation theory (PT) for the averaged J-point correlation functions, ξJξJ, with the results of numerical simulations of gravitational clustering. We carry out a systematic analysis of this me... Read More about A comparison of the evolution of density fields in perturbation theory and numerical simulations - II. Counts-in-cells analysis..

We present a detailed comparison of the predictions of second-order perturbation theory and numerical N-body simulations for the evolution of density fluctuations in a standard cold dark matter universe. The evolution of the power spectrum of density... Read More about A comparison of the evolution of density fields in perturbation theory and numerical simulations – I.
