ANISOTROPY OF COSMIC MICROWAVE BACKGROUND-RADIATION - A TEST FOR INFLATION AND OMEGA

The anisotropy properties of Cosmic Microwave Background Radiation (CM B) are discussed in the framework of the effect of mixing of geodesics in a universe with negative curvature. We study a crucial feature of the spots predicted by that mechanism, namely their elongated geometri cal shape. This feature should be absent in flat universe, particularl y in that having passed through an inflationary epoch. If future obser vations show the existence of this property on anisotropy maps, one ca n have serious indication of the negative curvature of the universe an d informative estimations for OMEGA and other cosmological parameters.
