Matter-Dark Energy Transition: A Dynamical Systems Approach
Bob Osano
In this study, we deviate from the traditional examination of the evolving universe through the scale factor and instead consider a parameter $\chiME$, defined by the ratio of two…

Dark Energy: A Dynamical Systems Approach to the Reconstruction of the Equation of State
Bob Osano
This correspondence delves into the application of dynamical systems methodologies within the context of cosmology, specifically addressing a preliminary strategy for determining t…

Dynamics of the transitions epochs in cosmological evolution
Bob Osano
We study two transition periods in cosmology: radiation-to-matter and matter-to-dark energy. In each case, we define a new parameter given by the ratios of the two energy densi…
