Inflation and dark energy from gravity
Michal Artymowski, Zygmunt Lalak, Marek Lewicki
Inflationary paradigm has several issues, such as the pre-inflationary horizon problem or the eternal inflation. To avoid that the standard Starobinsky inflation has been extended…
Saddle point inflation from higher order corrections to Higgs/Starobinsky inflation
Michal Artymowski, Zygmunt Lalak, Marek Lewicki
We explore two saddle point inflationary scenarios in the context of higher order corrections related to different generalisations of general relativity. Firstly, we deal with Jord…
Saddle point inflation from theory
Michal Artymowski, Zygmunt Lalak, Marek Lewicki
We analyse several saddle point inflationary scenarios based on power-law models. We investigate inflation resulting from $f(R) = R + α_n M^{2(1-n)}R^n + α_{n+1}M^{-2n}R^{n+…
