An Hamilton-Jacobi formulation of anisotropic inflation
Francesco Cicciarella, Joel Mabillard, Mauro Pieroni +1
Classifying inflationary scenarios according to their scaling properties is a powerful way to connect theory with observations. A useful tool to make such a classification is the b…

New perspectives on constant-roll inflation
F. Cicciarella, J. Mabillard, M. Pieroni
We study constant-roll inflation using the -function formalism. We show that the constant rate of the inflaton roll is translated into a first order differential equation for th…

Universality for quintessence
F. Cicciarella, M. Pieroni
Several recent works suggested the possibility of describing inflation by means of a renormalization group equation. In this paper we discuss the application of these methods to mo…
