Canonical quantization and constraint algebra of Weyl-invariant gravity in a conformal gauge: emergence of a geometric cosmological term

We present the canonical quantization of Weyl-invariant gravity in a specific conformal gauge. Fixing the scale factor as a(η)=1/(H0η) yields an effective geometric cosmological term M(η)=α/η2 on the left-hand side of the Einstein equations, guaranteeing an equation of state w=−1 by construction. The Bianchi identity r...
