Power spectrum of scalar fluctuations of the metric during the formation of a scalar black hole in inflation
José Edgar Madriz Aguilar, J. O. Valle, M. Montes +1
In this paper we use the collapse metric obtained by Carneiro and Fabris to calculate the power spectrum associated to gauge invariant fluctuations of the metric during the formati…

Power law coupling Higgs-Palatini inflation with a congruence between physical and geometrical symmetries
José Edgar Madriz Aguilar, Diego Allan Reyna, Mariana Montes
In this paper we investigate a power law coupling Higgs inflationary model in which the background geometry is determined by the Palatini's variational principle. The geometrical s…
