f(Q, T) gravity

Abstract We propose an extension of the symmetric teleparallel gravity, in which the gravitational action L is given by an arbitrary function f of the non-metricity Q and of the trace of the matter-energy-momentum tensor T, so that $$L=f(Q,T)$$ L=f(Q,T) . The field equations of the theory are obtain...
