Schouten-Codazzi Gravity
Roberto A Sussman, Sebastian Najera
We propose a new phenomenological second order gravity theory to be denoted as ''Schouten-Codazzi' Gravity'' (SCG), as it is based on Schouten and Codazzi tensors. The theory is re…
Cotton Gravity: the cosmological constant as spatial curvature
Roberto A Sussman, Sebastian Najera
We derive Friedman-Lemaitre-Robertson-Walker (FLRW) models as non-trivial solutions of "Cotton Gravity" (CG), a recently proposed gravity theory alternative to General Relativity (…
Exact solutions of Cotton Gravity in its Codazzi formulation
Roberto A Sussman, Sebastian Najera
The "Codazzi formulation", based on a Codazzi tensor, provides a more robust and straightforward theoretical framework for "Cotton Gravity" (CG) than its original formulation in te…
Fab-Four cosmography to tackle the Hubble tension
Celia Escamilla-Rivera, José María de Albornoz-Caratozzolo, Sebastián Nájera
In the context of the Fab-Four theory of gravity in a Friedmann-Lemaître-Robertson-Walker background, in this work we use the cosmography approach to study a particular self-tuning…
Geometric and physical properties of closed ever expanding dust models
Sebastián Nájera, Roberto A. Sussman
Current observations suggest that our Universe is not incompatible with a small positive spatial curvature that can be associated with rest frames having a "closed" standard topolo…
