The trace of the trace of the energy–momentum tensor-dependent Einstein's field equations

P Moraes - The European Physical Journal C, 2019 - Springer
The f (R, T) gravity field equations depend generically on both the Ricci scalar R and trace of
the energy–momentum tensor T. Within the assumption of perfect fluids, the theory carries …
