We analyze the possibility of inequivalent boundary conditions for a scalar field propagating in the BTZ black hole space-time. We find that for certain ranges of the black hole parameters, the Klein-Gordon operator admits a one-parameter family of self-adjoint extensions. For this range, the BTZ space-time is not quantum mechanically complete. We suggest a physically motivated method for determining the spectra of the Klein-Gordon operator.

Noncommutativity and the Weak Cosmic Censorship
hep-th 2019-08 reject novelty 5.0 of 10

Using a noncommutative duality, the authors claim that a high-energy scalar probe dresses a naked AdS3 singularity as a BTZ black hole, supporting weak cosmic censorship.
