### How universe evolves with cosmological and gravitational constants

(0 votes over all institutions)

We study a quantized Einstein-Cartan gravity and its ultraviolet unstable (stable) fixed point $\bar G_c\approx 0$ ($G_c\approx G_{\rm N}$) of running gravitational constant $G$. The cosmological constant $\Lambda\propto \xi^{-2}$ appears via a dimensional transmutation. The correlation length $\xi$ relates to the gravitational constant by a generalized Bianchi identity. Inflation possibly occurs in the neighborhood of fixed point $\bar G_c$, then universe evolves from $\bar G_c$ to $G_c$ as the space-time cutoff $\tilde a$ approaching to the Planck length $a_{\rm pl}$. The quantitative description of present universe in the scaling region of fixed point $G_c$ is given, and its deviation from the $\Lambda$CDM can be examined by recent cosmological observations, such as supernova Type Ia.
