Limits of the Rastall--Einstein Equivalence: Matter-Action Compatibility, FLRW Dynamics, and Exceptional Sectors
José A. C. Nogales, José A. C. Nogales, Karen-Luz Burgoa Rosso +1
A regular Rastall metric equation can be written exactly as an Einstein equation with a conserved algebraic source. We examine whether this source redefinition also preserves a spe…

Thermodynamics and Bouncing Cosmology in Rastall-like Gravity
José A. C. Nogales, K. Luz-Burgoa, Laysa G. Martins
In this study, we explore the thermodynamic aspects of a modified version of Rastall's gravity theory and its implications for cosmological scenarios. We analyze the role of non-co…
