Quasi-matter domination parameters in bouncing cosmologies
Emili Elizalde, Jaume Haro, Sergei D. Odintsov
For bouncing cosmologies, a fine set of parameters is introduced in order to describe the nearly matter dominated phase, and which play the same role that the usual slow-roll param…
Renormalization-group inflationary scalar electrodynamics and SU(5) scenarios confronted with Planck2013 and BICEP2 results
E. Elizalde, S. D. Odintsov, E. O. Pozdeeva +1
The possibility to construct inflationary models for the renormalization-group improved potentials corresponding to scalar electrodynamics and to and models is inve…
Functional Determinant of the Massive Laplace Operator and the Multiplicative Anomaly
G. Cognola, E. Elizalde, S. Zerbini
After a brief survey of zeta function regularization issues and of the related multiplicative anomaly, illustrated with a couple of basic examples, namely the harmonic oscillator a…
Inhomogeneous viscous dark fluid coupled with dark matter in the FRW universe
E. Elizalde, V. V. Obukhov, A. V. Timoshkin
A cosmological model with an inhomogeneous viscous dark fluid coupled with dark matter in a flat Friedman-Robertson-Walker universe is investigated. The influence of dark matter on…
