Complexity of the phase-space sheet. Simplex count and sheet volume in the ‘CDM’ simulations. This figure is exactly analogous to Fig. 15, but the left and right panels correspond to all the Vlasov CDM runs with box size L = 12.5 Mpc h⁻¹ and 25 Mpc h⁻¹, respectively, as listed in Table 1. Details on the curves are given in second left panel. Here, comparison with the Zel’dovich approximation in the bottom panels is lacking, but would provide qualitative results similar to those in bottom panels of Fig. 15.
