Non-minimal fluid Lagrangian couplings
Christian G. Boehmer, Erik Jensko, Eissa Al-Nasrallah
Gravitational models with non-minimal couplings involving functions of the matter Lagrangian and curvature have become popular in recent decades. By coupling the matter Lagrangian…
The choice of variables in cosmological dynamical systems
Christian G. Boehmer, Antonio d'Alfonso del Sordo
Dynamical systems techniques are a powerful tool to analyse systems of ordinary differential equations, written in an appropriate form. For a given theory of gravity, the cosmologi…
Dynamical systems approach to stellar modelling in gravity
Sudan Hansraj, Christian G. Boehmer, Ndumiso Buthelezi
The novel proposal to invoke the split of the Ricci scalar into bulk and boundary terms in the gravitational action, opens up a new avenue of investigation into stellar dynamics. T…
