Scientific paper

The anisotropy properties of cosmic microwave background radiation (CMB) are discussed in the framework of the effect of mixing of geodesics in a universe with negative curvature. The authors study a crucial feature of the spots predicted by that mechanism, namely their elongated geometrical shape. This feature should be absent in a flat universe, particularly in that having passed through an inflationary epoch. If future observations show the existence of this property on anisotropy maps, one can have serious indication of the negative curvature of the universe and informative estimations for Ω and other cosmological parameters.
