Radial canonical $\mathrm{\Lambda }<0$ gravity

We apply an ADM deparametrization strategy to radial canonical $\mathrm{\Lambda }<0$ gravity in three dimensions. It gives rise to a concise notation for previous holographic interpretations in terms of an identified radial ‘volume time’ and ‘true’ ADM degrees of freedom. We further discuss York time and conformal boundary conditions in this context, and construct a BTZ wavepacket solution to the radial WdW equation.
