| contents | In this study, we deviate from the traditional examination of the evolving universe through the scale factor and instead consider a parameter \(χ_{ME}\), defined by the ratio of two competing energy densities: matter (DM) and dynamic dark energy (DDE). While the scale factor's role is not neglected, it is inherently embedded within the evolution equations of these competing energy densities. By employing dynamical systems techniques, we investigate the behaviour of this ratio \(χ_{ME}\) to understand the dynamics surrounding the cosmological transition from matter domination to dark energy domination. This methodological shift allows for a more nuanced analysis of the matter-to-dark energy transition. |
