Asymptotic dynamical analysis of $f (R, T^{ϕ}) = R + α T^{ϕ} + β (T^{ϕ})^{2} /2$ cosmology

Joaquin Estevez-Delgado, Roberto De Arcia, Gabino Estevez-Delgado +1

In this work we investigate the asymptotic cosmological dynamics of a modified gravity model based on the $f (R, T^{ϕ})$ theory, where $R$ denotes the Ricci scalar and $T^{ϕ}$ is the tra…

On local scale invariance and the questionable theoretical basis of the conformal transformations' issue

Israel Quiros, Roberto De Arcia

Here we follow the mainstream of thinking about physical equivalence of different representations of a theory, regarded as the consequence of invariance of the laws of physics -- r…
