Modifications of the Purely Geometric Sector,s are given by scalars constructed on the base of the metric tensor, i.e. these scalars are functions of the Riemann tensor, the Ricci tensor, possibly, their covariant derivatives, and the scalar curvature.

保全

Horava-Lifshitz Gravity,the Einstein gravity is non-renormalizable since the mass dimension of the gravitational constant is negative. The natural improvement of a situation could consist in adding the higher derivative terms which clearly make the UV asymptotics of the propagator better.

Summary, comments on non-Riemannian gravity models. As we noted, in principle there are two fundamental problems to be solved by the desired modifications of gravity: first, explanation of the cosmic acceleration, and, second, development of a theory consistent from a quantum viewpoint.
