Black hole formation and slow-roll inflation
Kazunori Kohri, David H. Lyth, Alessandro Melchiorri
Black hole formation may occur if the spectrum of the curvature perturbation ζincreases strongly as the scale decreases. As no such increase is observed on cosmological scales, bla…

More hilltop inflation models
Kazunori Kohri, Chia-Min Lin, David H. Lyth
Using analytic expressions, we explore the parameter space for hilltop inflation models with a potential of the form . With the positive sign and p>2 this conv…

The curvature perturbation in a box
David H. Lyth
The stochastic properties of cosmological perturbations are best defined through the Fourier expansion in a finite box. I discuss the reasons for that with reference the curvature…
