Stability of non-degenerate Ricci-type Palatini theories
Jaakko Annala, Syksy Rasanen
We study the stability of theories where the gravitational action has arbitrary algebraic dependence on the three first traces of the Riemann tensor: the Ricci tensor, the co-Ricci…

Higgs inflation and higher-order gravity in Palatini formulation
Jaakko Annala
We study how higher-order gravity affects Higgs inflation in the Palatini formulation. We first review the metric and Palatini formulations in comparative manner and discuss their…
