英文摘要	We quantify the accuracy with which the cosmological parameters characterizing the energy density of matter (Omega(m)), the amplitude of the power spectrum of matter fluctuations (sigma(8)), the energy density of neutrinos (Omega(nu)) and the dark energy equation of state (w(0)) can be constrained using data from large galaxy redshift surveys. We advocate a joint analysis of the abundance of galaxies, galaxy clustering, and the galaxy-galaxy weak-lensing signal in order to simultaneously constrain the halo occupation statistics (i.e. galaxy bias) and the cosmological parameters of interest. We parametrize the halo occupation distribution of galaxies in terms of the conditional luminosity function and use the analytical framework of the halo model described in Cacciato et al. (our companion Paper III), to predict the relevant observables. By performing a Fisher matrix analysis, we show that a joint analysis of these observables, even with the precision with which they are currently measured from the Sloan Digital Sky Survey, can be used to obtain tight constraints on the cosmological parameters, fully marginalized over uncertainties in galaxy bias. We demonstrate that the cosmological constraints from such an analysis are nearly uncorrelated with the halo occupation distribution constraints, thus, minimizing the systematic impact of any imperfections in modelling the halo occupation statistics on the cosmological constraints. In fact, we demonstrate that the constraints from such an analysis are both complementary to and competitive with existing constraints on these parameters from a number of other techniques, such as cluster abundances, cosmic shear and/or baryon acoustic oscillations, thus paving the way to test the concordance cosmological model.
