  This paper reviews selected aspects of the growth of cosmological structure,
covering the following general areas: (1) expected characteristics of linear
density perturbations according to various candidate theories for the origin of
structure; (2) low-order theory for statistical measures of fluctuations; (3)
formation of nonlinear structures and nonlinear evolution of the mass
distribution; (4) the relation between the density field and the galaxy
distribution; (5) constraints on cosmological models from galaxy clustering and
its evolution.
