It is assumed that clusters of galaxies evolve from high peaks in the primordial density fluctuation field which can be described by a Gaussian field. From a statistical analysis of peaks in the fluctuation field and the assumption of linear evolution of the density fluctuations a distribution function for the mass and amplitude of protocluster density fluctuations can be derived. Using plausible physical scaling laws and observationally determined parameters these distribution functions can be converted into the x-ray luminosity function of galaxy clusters which can in turn be compared with observations. The goal of this analysis (which is still in progress) is a theoretical model that allows for direct comparison with x-ray observations and involves only one scaling factor as open parameter once the form of the power spectrum of the primordial density fluctuations have been chosen.
