abstract
The curvature coordinates $T,R$ of a Schwarz\-schild spacetime are turned into canonical coordinates $T(r), {\sf R}(r)$ on the phase space of spherically symmetric black holes. The entire dynamical content of the Hamiltonian theory is reduced to the constraints requiring that the momenta $P_{T}(r), P_{\sf R}(r)$ vanish. What remains is a conjugate pair of canonical variables $m$ and $p$ whose values are the same on every embedding. The coordinate $m$ is the Schwarzschild mass, and the momentum $p$ the difference of parametrization times at right and left infinities. The Dirac constraint quantization in the new representation leads to the state functional $\Psi (m; T, {\sf R}] = \Psi (m)$ which describes an unchanging superposition of black holes with different masses. The new canonical variables may be employed in the study of collapsing matter systems.

Schr\"odinger Symmetry in Spherically-symmetric Static Mini-superspaces with Matter Fields
Spherically symmetric static gravity with Maxwell or massless-scalar matter exhibits Schrödinger symmetry after a canonical transformation, yielding (A)dS-Reissner-Nordström and generalized Janis-Newman-Winicour solutions.

Affine quantization of the dynamical Reissner--Nordstr\"om region
Affine quantization of the Reissner-Nordström dynamical region yields separable Wheeler-DeWitt solutions with Hermite-polynomial and Gaussian modes, plus short-distance modifications from the quantization procedure.

Orbital Dynamics and Gravitational-Wave Signatures of EMRIs in Self-Dual Loop Quantum Gravity Black Holes
The paper computes EMRI orbits and waveforms in self-dual LQG black hole spacetimes and claims Fisher-matrix constraints on the quantum parameters P and a0, but the Fisher forecast uses the metric itself as the observable.

Quasinormal Modes of Self-Dual Loop Quantum Gravity Corrected Kerr Black Holes
In a rotating LQG-corrected black hole model, the polymeric parameter P lowers scalar quasinormal-mode frequencies, while spin raises them.

Aspects of Geometrodynamics in the Jordan and Einstein Frames
The Jordan and Einstein frames are connected by a Hamiltonian canonical transformation only after gauge-fixing lapse and shift, and this maps the FJNW naked singularity to the BBMB black hole.
