On certain cosmological relics of the early string dynamics

The tracing of cosmological relics from the early string dynamics may enhance the theory and provide new perspectives on the major cosmological problems. This point is illustrated in a leading-order Bianchi type VII0 string background, wherein spatial isotropy can be claimed as such a relic, albeit a gross one. A much finer relic, descending from a primordial gravitational wave, could be retrieved from its imprint on the small-scale structure of the cosmic microwave background. In spite of the absence of conventional inflation, there is no horizon problem thanks to the presence of an equally fundamental Mixmaster dynamics. Implications and certain new perspectives which thus arise for the more general problem of cosmological mixing are briefly discussed.
