Remarks on 2D quantum cosmology

Understand

We consider two-dimensional quantum gravity endowed with a positive cosmological constant and coupled to a conformal field theory of large and positive central charge.

• We study cosmological properties at the classical and quantum level.
• We provide a complete ADM analysis of the classical phase space, revealing a family of either bouncing or big bang/crunch type cosmologies.
• At the quantum level, we solve the Wheeler-DeWitt equation exactly.
