A correspondence between modified gravity and General Relativity with scalar fields
Victor I. Afonso, Gonzalo J. Olmo, Emanuele Orazi +1
We describe a novel procedure to map the field equations of nonlinear Ricci-based metric-affine theories of gravity, coupled to scalar matter described by a given Lagrangian, into…
Mapping nonlinear gravity into General Relativity with nonlinear electrodynamics
Victor I. Afonso, Gonzalo J. Olmo, Emanuele Orazi +1
We show that families of nonlinear gravity theories formulated in a metric-affine approach and coupled to a nonlinear theory of electrodynamics can be mapped into General Relativit…
Coupling matter in modified -gravity
Tiberiu Harko, Tomi S. Koivisto, Francisco S. N. Lobo +2
We present a novel theory of gravity by considering an extension of symmetric teleparallel gravity. This is done by introducing, in the framework of the metric-affine formalism, a…
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…
Mapping Ricci-based theories of gravity into general relativity
V. I. Afonso, Gonzalo J. Olmo, D. Rubiera-Garcia
We show that the space of solutions of a wide family of Ricci-based metric-affine theories of gravity can be put into correspondence with the space of solutions of general relativi…
