The Distorted Wheeler-DeWitt Equation

The Wheeler-DeWitt Equation represents a tool to study Quantum Gravity and Quantum Cosmology. Its solution in a very general context is, of course, impossible. To this purpose we consider some distortions of General Relativity like Gravity’s Rainbow, Varying Speed of Light Cosmology, Generalized Uncertainty Principle deformations and Ho\v{r}ava-Lifshitz gravity which could allow the calculation of some observables like the cosmological constant. For simplicity we consider only the Mini-Superspace approach related to a Friedmann-Lema^itre-Robertson-Walker space-time.
