A new framework for cosmological expansion in a reformulated Newtonian-Like gravity with variable G
Felipe S. Escórcio, Júlio C. Fabris, Júnior D. Toniato +1
A Newtonian-like theory inspired by the Brans-Dicke gravitational Lagrangian has been recently proposed in Ref. arXiv:2009.04434(v4). We propose here a new variant of this theory s…

Holographic Ricci dark energy in Nonconservative Unimodular Gravity
Marcelo H. Alvarenga, Júlio C. Fabris, Hermano Velten +1
The structure of unimodular gravity (UG) is invariant to a subclass of diffeomorphism, the transverse diffeomorphism, due to the unimodular condition (). Consequen…
