Observable Quantities in Weyl Gravity

Abstract

In this paper, the cosmological "constant" and the Hubble parameter are considered in the Weyl theory of gravity, by taking them as functions of $r$ and $t$, respectively. Based on this theory and in the linear approximation, we obtain the values of $H_0$ and ${\Lambda }_0$ which are in good agreement with the known values of the parameters for the current state of the universe.
