TL;DR: Euclid is a European Space Agency medium-class mission selected for launch in 2020 within the cosmic vision 2015-2025 program as discussed by the authors, which will explore the expansion history of the universe and the evolution of cosmic structures by measuring shapes and red-shift of galaxies as well as the distribution of clusters of galaxies over a large fraction of the sky.

TL;DR: The Large Synoptic Survey Telescope (LSST) as discussed by the authors will have an effective aperture of 6.7 meters and an imaging camera with field of view of 9.6 degrees.

TL;DR: This review is meant to provide a guide to the scientific themes that will underlie the activity of the group during the preparation of the Euclid mission and discusses five broad topics: dark energy and modified gravity, dark matter, initial conditions, basic assumptions and questions of methodology in the data analysis.

TL;DR: In this article, the authors derived model-independent constraints on the dark energy density rho_X(z) and the cosmic expansion rate H(z), and also derived constraints on dark energy equation of state w X(z)=w_0+w'z (with cutoff at z=2) and w X (a)=w 0+1-a)w_a.

TL;DR: In this article, the authors derived model-independent constraints on the dark energy density ρX(z) and the cosmic expansion rate H(z), and also derived constraints on wX (z) = w0 + w'z (with cutoff at z = 2).
