$$\kappa (R,T)$$ κ(R,T) gravity
Abstract In this note we explore a modified theory of gravitation that is not based on the least action principle, but on a natural generalization of the original Einstein’s field equations. This approach leads to the non-covariant conservation of the stress-energy tensor, a feature shared with othe...
