Inflationary universe in terms of a van der Waals viscous fluid
I. Brevik, E. Elizalde, S. D. Odintsov +1
The inflationary expansion of our early-time universe is considered in terms of the van der Waals equation, as equation of state for the cosmic fluid, where a bulk viscosity contri…
Inhomogeneous imperfect fluid inflation
Emilio Elizalde, Luis G. T. Silva
A generalized equation of state corresponding to a model that includes a Chaplygin gas and a viscous term is investigated, in the context of the reconstruction program in scalar fi…
Inflationary Universe with a Viscous Fluid Avoiding Self-Reproduction
I. Brevik, E. Elizalde, V. V. Obukhov +1
We consider a universe with a bulk viscous cosmic fluid, in a flat Friedmann-Lemaitre-Robertson-Walker geometry. We derive the conditions for the existence of inflation, and those…
Viscous Little Rip Cosmology
I. Brevik, E. Elizalde, S. Nojiri +1
Dark energy of phantom or quintessence nature with an equation of state parameter almost equal to -1 often leads the universe evolution to a finite-time future singularity. An…
Universal procedure to cure future singularities of dark energy models
A. J. López-Revelles, E. Elizalde
A systematic search for different viable models of the dark energy universe, all of which give rise to finite-time, future singularities, is undertaken, with the purpose to try to…
Spherical systems in models of nonlocally corrected gravity
K. A. Bronnikov, E. Elizalde
The properties of static, spherically symmetric configurations are considered in the framework of two models of nonlocally corrected gravity, suggested in S. Deser and R. Woodard.,…
