Acceptable cosmologies with wave maps

Not scheduled
Oral presentation


Dr Koralia Tzanni (University of the Aegean)


We consider theories of gravity that include many coupled scalar fields with arbitrary couplings, in the geometric framework of wave maps. The possibility of obtaining acceptable cosmological solutions without the inclusion of a potential term to the scalar fields is examined. We also address the issue of the conditions that must be satisfied by the wave maps for an accelerated phase of the Universe.
