Query: Scaling solutions for Dilaton Quantum Gravity   Scaling solutions for the effective action in dilaton quantum gravity are
investigated within the functional renormalization group approach. We find
numerical solutions that connect ultraviolet and infrared fixed points as the
ratio between scalar field and renormalization scale $k$ is varied. In the
Einstein frame the quantum effective action corresponding to the scaling
solutions becomes independent of $k$.
  The field equations derived from this effective action can be used directly
for cosmology. Scale symmetry is spontaneously broken by a non-vanishing
cosmological value of the scalar field. For the cosmology corresponding to our
scaling solutions, inflation arises naturally. The effective cosmological
constant becomes dynamical and vanishes asymptotically as time goes to
infinity.
