Noncoincidence -Cosmology with Dark Matter Coupled to Gravity
A. Abebe, P. S. Apostolopoulos, A. Giacomini +3
We investigate FLRW cosmology in the framework of symmetric teleparallel gravity with a nonminimal coupling between dark matter and the gravitational field. In the noncoinci…

Anisotropic Spacetimes in -gravity: Bianchi I, Bianchi III and Kantowski-Sachs Cosmologies
R. Bogadi, A. Giacomini, M. Govender +3
We investigate the evolution of cosmological anisotropies within the framework of -gravity. Specifically, we consider a locally rotationally symmetric geometry in…

-cosmological dynamics in the FLRW background
Nikolaos Dimakis, Alex Giacomini, Genly Leon +3
We examine the cosmological dynamics of Einstein-Gauss-Bonnet gravity models in a four-dimensional spatially flat FLRW metric. These models are described by $f\left( R,\mathcal{G}\…
