A new 2D formulation of modified General Relativity
Christian G. Boehmer, Erik Jensko
It is well known that the Einstein-Hilbert action in two dimensions is topological and yields an identically vanishing Einstein tensor. Consequently one is faced with difficulties…

Dynamical systems analysis of gravity
Christian G. Boehmer, Erik Jensko, Ruth Lazkoz
Modified gravity theories can be used for the description of homogeneous and isotropic cosmological models through the corresponding field equations. These can be cast into systems…

Modified gravity: a unified approach to metric-affine models
Christian G. Boehmer, Erik Jensko
The starting point of this work is the original Einstein action, sometimes called the Gamma squared action. Continuing from our previous results, we study various modified theories…
