Scientific paper

We propose a geometrical framework which is adapted for the investigation of large-scale structures at high redshifts in curved spaces, within the standard world model of the Universe. It is based on the embedding of the comoving space into the 4D metric space, which provides us with a useful algebraic representation of the positions of objects in space. In particular, the interpretation and the calculation of geometrical quantities, such as distances between objects, angles, surfaces and volumes, become obvious. Moreover, elements of cartography provide us with a global view of the Universe which accounts for the curvature. A quasar catalogue is used for observational support. This framework is implemented in a routine called UNIVERSE VIEWER.†
