A PRIMORDIAL COSMOLOGICAL SCENARIO WITH 2 SCALAR FIELDS AND MATTER

The presence of matter in its different forms in a hexadimensional spa ce-time, where gravitation is coupled to a conformal held, generates a class of cosmological solutions with very peculiar features: the init ial proper distance between any two points of the space-time is infini te, following successive contraction and expansion phases in the evolu tion of the Universe. This behaviour defines a Anti-Big Bang Singular Cosmology. In this article we analyze this primordial cosmological sce nario considering different matter forms and the effects of a Conforma l Transformation on the metric.
