Dynamical systems in cosmology
Christian G. Boehmer, Nyein Chan
Cosmology is a well established research area in physics while dynamical systems are well established in mathematics. It turns out that dynamical system techniques are very well su…
Dynamics of dark energy models and centre manifolds
Christian G. Boehmer, Nyein Chan, Ruth Lazkoz
We analyse dark energy models where self-interacting three-forms or phantom fields drive the accelerated expansion of the Universe. The dynamics of such models is often studied by…
Quintessence with quadratic coupling to dark matter
Christian G. Boehmer, Gabriela Caldera-Cabral, Nyein Chan +2
We introduce a new form of coupling between dark energy and dark matter that is quadratic in their energy densities. Then we investigate the background dynamics when dark energy is…
