The dark energy crossing of the cosmological constant boundary (the transition between the quintessence and phantom regimes) is described in terms of the implicitly defined dark energy equation of state. The generalizations of the models explicitly constructed to exhibit the crossing provide the insight into the cancellation mechanism which makes the transition possible. The determination of th...

We have investigated the model of dark energy interacting with dark matter by choosing inhomogeneous equations of state for the dark energy and a non-linear interaction term for the underlying interaction. The equations of state have dependencies either on the energy densities, the redshift, the Hubble parameter or the bulk viscosity. We have considered these possibilities and have derived the ...

A new surface energy-value for dark matter is calculated, derivated from a perspective of a “higher order universe“. A universe of dark energy, darkand visible matter, and a dark energy force. A fundamental connection between dark matter and visible matter is related to dark energy (viXra-paper 1010.0014 in particular is the reference for this novum . The surface energy-density of dark matter s...
