Stability of a Schwarzschild Singularity
TLDR
In this article, it was shown that a Schwarzschild singularity, spherically symmetrical and endowed with mass, will undergo small vibrations about the spherical form and therefore remain stable if subjected to a small nonspherical perturbation.Abstract:

Quasinormal modes of five-dimensional black holes in non-commutative geometry
TL;DR: In this article, the spectrum of quasinormal frequencies of five-dimensional black holes obtained in noncommutative geometry was computed and scalar perturbations of a massive scalar field adopting the 6th order WKB approximation were studied.
