A Finite Measure for the Initial Conditions of Inflation
Kieran Finn, Sotirios Karamitsos
We investigate whether inflation requires finely tuned initial conditions in order to explain the degree of flatness and homogeneity observed in the Universe. We achieve this by us…
The Eisenhart Lift for Field Theories
Kieran Finn, Sotirios Karamitsos, Apostolos Pilaftsis
We present the Eisenhart-lift formalism in which the dynamics of a system that evolves under the influence of a conservative force is equivalent to that of a free system embedded i…
On the Cosmological Frame Problem
Sotirios Karamitsos, Apostolos Pilaftsis
We introduce a fully-frame covariant formalism for inflation by taking into account conformal transformations in addition to field reparametrizations. We begin by providing a brief…
