Two-fluid matter-quintessence FLRW models: energy transfer and the equation of state of the universe

A. Gromov, Yu. Baryshev, P. Teerikorpi

Recent observations support the view that the universe is described by a FLRW model with ${\Omega }_m^0\approx 0.3$, ${\Omega }_{\Lambda }^0\approx 0.7$, and $w\le -1/3$ at the present epoch. There are…
