Phase space analysis and singularity classification for linearly interacting dark energy models
Muhsin Aljaf, Daniele Gregoris, Martiros Khurshudyan
In this paper, applying the Hartman-Grobman theorem we carry out a qualitative late-time analysis of some unified dark energy-matter Friedmann cosmological models, where the two in…
