Extending Friedmann equations using fractional derivatives using a Last Step Modification technique: the case of a matter dominated accelerated expanding Universe

E. Barrientos, S. Mendoza, P. Padilla

We present a toy model for extending the Friedmann equations of relativistic cosmology using fractional derivatives. We do this by replacing the integer derivatives, in a few well-…

Non-vacuum relativistic extensions of MOND using metric theories of gravity with curvature-matter couplings and their applications to the accelerated expansion of the Universe without dark components

E. Barrientos, T. Bernal, S. Mendoza

We discuss the advantages of using metric theories of gravity with curvature-matter couplings in order to construct a relativistic generalisation of the simplest version of Modifie…

MOND as the weak field limit of an extended metric theory of gravity with a matter-curvature coupling

E. Barrientos, S. Mendoza

In this article we construct an extended relativistic f(R) theory of gravity with matter-curvature couplings F(R,L_matt) for which its weak field limit of approximation recovers th…

Metric-affine f(R,T) theories of gravity and their applications

E. Barrientos, Francisco S. N. Lobo, S. Mendoza +2

We study f(R,T) theories of gravity, where T is the trace of the energy-momentum tensor T_{μν}, with independent metric and affine connection (metric-affine theories). We find that…

MOND as the weak field limit of an extended metric theory of gravity with torsion

E. Barrientos, S. Mendoza

In this article we construct a relativistic extended metric theory of gravity, for which its weak field limit reduces to the non-relativistic MOdified Newtonian Dynamics regime of…

A relativistic description of MOND using the Palatini formalism in an extended metric theory of gravity

E. Barrientos, S. Mendoza

We construct a relativistic metric description of MOND using the Palatini formalism following the \( f(χ)=χ^b \) description of \citet{mendozatula}. We show that in order to recove…
