Abstract
We discuss AdS quantum gravity from an unconventional perspective that emphasizes bulk geometry. In our approach, AdS has no boundary, there are no divergences that require renormalization, and the dilaton of JT-gravity can be omitted altogether. The result is the standard Schwarzian theory. However, it may be advantageous that our derivation just relies on conventional AdS/CFT correspondence and effective quantum field theory. For example, it clarifies the symmetry breaking pattern. It also puts the non-compact AdS topology on the same footing as compact Riemann surfaces.
