The Peebles -- Vilenkin quintessential inflation model revisited
Jaume Haro, Jaume Amorós, Supriya Pan
We review the well-known Peebles-Vilenkin (PV) quintessential inflation model and discuss its possible improvements in agreement with the recent observations. The improved PV model…
Discrepancies between observational data and theoretical forecast in single field slow roll inflation
Jaume Amorós, Jaume de Haro
The PLANCK collaboration has determined values for the spectral parameters of the CMB radiation, namely the spectral index , its running , the running of the running $β_s…
The twilight of the single field slow rolling inflaton
Jaume Amoros, Jaume de Haro
We present an study from PLANCK2013+WP+BAO:CDM++ data, where 49 slow roll inflationary potentials are tested, showing that the theoretical value of the running provided…
Non-singular models of universes in teleparallel theories
Jaume de Haro, Jaume Amoros
Different models of universes are considered in the context of teleparallel theories. Assuming that the universe is filled by a fluid with equation of state (EoS) , for…
On the fate of the phantom dark energy universe in semiclassical gravity II: Scalar phantom fields
Jaume de Haro, Jaume Amoros, Emilio Elizalde
Quantum corrections coming from massless fields conformally coupled with gravity are studied, in order to see if they can lead to avoidance of the annoying Big Rip singularity whic…
Deformations of Kahler manifolds with non vanishing holomorphic vector fields
Jaume Amoros, Monica Manjarin, Marcel Nicolau
In this article we study compact Kähler manifolds admitting non-singular holomorphic vector fields with the aim of extending to this setting the classical birational classifica…
Symplectic Lefschetz fibrations with arbitrary fundamental groups
J. Amorós, F. Bogomolov, L. Katzarkov +2
In this paper we give an explicit construction of a symplectic Lefschetz fibration whose total space is a smooth compact four dimensional manifold with a prescribed fundamental gro…
On the Malcev completion of Kähler groups
Jaume Amoros
Restrictions are placed on the presentation and holonomy algebra of a Kähler group. Let be compact Kähler. It is known that the formality of , its Albanese map and the Hodge…
