Generalizing the coupling between geometry and matter: $$f\left( R,L_m,T\right) $$ f R , L m , T gravity
Abstract We generalize and unify the $$f\left( R,T\right) $$ f R , T and $$f\left( R,L_m\right) $$ f R , L m type gravity models by assuming that the gravitational Lagrangian is given by an arbitrary function of the Ricci scalar R, of the trace of the energy–momentum tensor T, and of the matter Lagr...
