Loop quantum gravity - a short review
read the original abstract
In this article we review the foundations and the present status of loop quantum gravity. It is short and relatively non-technical, the emphasis is on the ideas, and the flavor of the techniques. In particular, we describe the kinematical quantization and the implementation of the Hamilton constraint, as well as the quantum theory of black hole horizons, semiclassical states, and matter propagation. Spin foam models and loop quantum cosmology are mentioned only in passing, as these will be covered in separate reviews to be published alongside this one.

Spherically symmetric solutions in quasi-local Einstein-Weyl gravity
In quasi-local Einstein-Weyl gravity, static spherically symmetric Frobenius solutions are classified: regular cores only, Schwarzschild-like horizons and wormhole throats, plus asymptotic 1/r^6 corrections to Schwarzschild.

Perturbative Renormalisation Group Improved Black Hole Solution and its Quasinormal Modes
A second-order RG-improved Schwarzschild-(A)dS metric is derived and its scalar QNMs are shown to depend weakly on the free parameter ζ, with consistent results from WKB, shooting, and matrix-pencil time-domain analysis.
