Abstract
The spatial two point galaxy correlation function, ξ( r ), is, at present, the most useful statistic for comparing theoretical models to observational data. We have derived expressions for the dynamical evolution of ξ for structures arising from Gaussian initial conditions under the assumption that non-linear evolution may be described by the Zel'dovich approximation. The observed angular correlation function, w (θ), places constraints on the spectrum of initial fluctuations on large scales.
