摘　　要：The comparison between the amplitude of density fluctuations in matter today as inferred from the observations of the Cosmic Microwave background by the Planck collaboration [1] to that from the observations of the late Universe,is a stringent test of the concordance cosmological model. A joint analysis of the clustering of galaxies and their galaxygalaxy lensing signal is a unique way to constrain cosmological parameters.
