Gravity from the determinant of the energy-momentum: Astrophysical implications
Determinants of the second rank tensors stand useful in forming generally invariant terms as in the case of the volume element of the gravitational actions. Here, we extend the action of the matter fields by an arbitrary function f(D) of the determinants of their energy-momentum, and the metric, D=|...
