Tilt in quadratic gravity II
Waleska P. F. de Medeiros, Daniel Müller, Oliver F. Piattella +2
We investigate a tilted fluid component on a Bianchi V geometry in the theories of General Relativity (GR) and Quadratic Gravity (QG). The main objective of this work is the study…

On the order reduction
Waleska P. F. de Medeiros, Daniel Müller
In this work we present an extension of the technique of the order reduction to higher perturbative approximations in an iterative fashion. The intention is also to analyze more ca…
