Note on bouncing backgrounds
(American Physical Society (APS), 2018-05-15)
Article
Accés obertThe theory of inflation is one of the fundamental and revolutionary developments of modern cosmology that became able to explain many issues of the early Universe in the context of the standard cosmological model (SCM). ... -
Viable inflationary evolution from Einstein frame loop quantum cosmology
(American Physical Society (APS), 2018-04-27)
Article
Accés obertIn this work we construct a bottom-up reconstruction technique for loop quantum cosmology scalar-tensor theories, from the observational indices. Particularly, the reconstruction technique is based on fixing the functional ... -
Bulk viscous quintessential inflation
(2018-04-01)
Article
Accés restringit per política de l'editorialIn a spatially-flat Friedmann–Lemaître–Robertson–Walker universe, the incorporation of bulk viscous process in general relativity leads to an appearance of a nonsingular background of the universe that both at early and ... -
Antisymmetry of solutions for some weighted elliptic problems
(2018-03-17)
Article
Accés restringit per política de l'editorialThis article concerns the antisymmetry, uniqueness, and monotonicity properties of solutions to some elliptic functionals involving weights and a double well potential. In the one-dimensional case, we introduce the continuous ... -
Planelike minimizers of nonlocal Ginzburg-Landau energies and fractional perimeters in periodic media
(2018-07-01)
Article
Accés obertWe consider here a nonlocal phase transition energy in a periodic medium and we construct solutions whose interfaces lie at a bounded distance from any given hyperplane. These solutions are either periodic or quasiperiodic, ... -
Regularity of radial stable solutions to semilinear elliptic equations for the fractional laplacian
(2018-11-01)
Article

Reheating constraints in quintessential inflation
(2017-06-02)
Article
Accés obertWe study the consequences of reheating in quintessential inflation. From simple inflationary quintessential models introduced by de Haro, Amorós, and Pan in [Phys. Rev. D 93, 084018 (2016)] and [Phys. Rev. D 94, 064060 ... -
Instability and bifurcation in a trend depending price formation model
(2016-08)
Article
Accés obertA well-known model due to J.-M. Lasry and P.L. Lions that presents the evolution of prices in a market as the evolution of a free boundary in a diffusion equation is modified in order to show instabilities for some values ... -
Convergence to steady-state and boundary layer profiles in a linear chromatography system
(2015-01-01)
Article
Accés restringit per política de l'editorialWe study the hyperbolic system of equations of the so-called linear transport model in a true moving bed chromatography device with four ports. By using methods based on a suitable energy functional we show that all solutions ... -
Quintessential inflation at low reheating temperatures
(2017-11-23)
Article
Accés obertWe have tested some simple quintessential inflation models, imposing the requirement that they match with the recent observational data provided by the BICEP and Planck team and leading to a reheating temperature, which ... -
Reheating via gravitational particle production in simple models of quintessence or ¿CDM Inflation
(2017-11-14)
Article
Accés obertWe have tested some simple CDM (the same test is also valid for quintessence) inflation models, imposing that they match with the recent observational data provided by the BICEP and Planck’s team and leading to a reheating ... -
Delaunay hypersurfaces with constant nonlocal mean curvature
(2017-08-12)
Article
Accés restringit per política de l'editorialWe study hypersurfaces of RN with constant nonlocal (or fractional) mean curvature. This is the equation associated with critical points of the fractional perimeter functional under a volume constraint. We establish the ...
