Non-linear interactions in cosmologies with energy exchange
John D. Barrow, Georgia Kittou
We investigate the case of two interacting fluids in homogeneous and isotropic cosmologies with a non-linear interaction term. The interaction term avoids the unrealistic form gene…
Cosmological wave maps
Spiros Cotsakis, John Miritzis, Koralia Tzanni
We consider theories of gravity that include many coupled scalar fields with arbitrary couplings, in the geometric framework of wave maps. We examine the possibility of obtaining a…
Interacting vacuum at infinity
Georgia Kittou
We apply the central extension technique of Poincare to dynamics involving an interacting mixture of pressureless matter and vacuum near a finite-time singularity. We show that the…
