The conformal cosmological potential
Spiros Cotsakis, Ifigeneia Klaoudatou, Georgios Kolionis +2
We discuss qualitative features of the conformal relation between certain classes of gravity theories and general relativity, common to different themes such as , Brans-Dicke…
Cosmological Asymptotics in Higher-Order Gravity Theories
Georgios Kolionis
We study the early-time behavior of isotropic and homogeneous solutions in vacuum as well as radiation-filled cosmological models in the full, effective, four dimensional gravity t…
Asymptotic vacua with higher derivatives
Spiros Cotsakis, Seifedine Kadry, Georgios Kolionis +1
We study limits of vacuum, isotropic universes in the full, effective, four-dimensional theory with higher derivatives. We show that all flat vacua as well as general curved ones a…
Asymptotic states of generalized universes with higher derivatives
Spiros Cotsakis, Georgios Kolionis, Antonios Tsokaros
We review ongoing research related to the asymptotic dynamics of isotropic universes in theories with higher derivatives, especially near the initial singularity. We treat two majo…
