What is in the black box of dark energy: variable cosmological parameters or multiple (interacting) components?
The unknown nature of dark energy reflects itself in a number of puzzling properties of the present Universe, comprising the coincidence problem of the presently comparable energy densities of nonrelativistic matter and dark energy and the peculiarities of the possible evolution of the dark energy equation of state. A solution of these problems can be sought by considering dark energy as an effective description of alternative cosmological models. An effective dark energy behavior of the cosmological models with variable parameters as well as the composite models of dark energy is presented. Implications of these cosmological problems to the coincidence problem and a possible cosmological constant boundary crossing are discussed.
