Abstract
Applying the higher order holonomy corrections to the perturbation theory of cosmology, the lattice power law of loop quantum cosmology, , is analyzed and the range of β is decided to be [−1,0] which is different from the conventional range −0.1319 > β ⩾ −5/2 (Bojowald M and Hossain G M 2008 Phys. Rev. D 77 023508). At the same time, we find that there is an anomaly-free condition in this theory, and we obtain this condition in the vector and tensor mode. We also find that the nonzero mass of a gravitational wave essentially results from the quantum nature of the Riemannian geometry of loop quantum gravity.
