Title: Evolution of large-scale structure in a universe dominated by cold dark matter

Abstract

We present the results of numerical simulations of nonlinear gravitational clustering in universe dominated by weakly interacting, ''cold'' dark matter (e.g., axions or photinos). These studies employ a high resolution N-body code with periodic boundary conditions and 32,768 particles; they can accurately represent the theoretical initial conditions over a factor of 16 in length scale. We have followed the evolution of ensembles of models with ..cap omega.. = 1 and ..cap omega.. < 1 from the initial conditions predicted for a ''constant curvature'' primordial fluctuation spectrum.
