Weak cosmic censorship conjecture in Myers-Perry black hole with separability

We investigate the weak cosmic censorship conjecture in Myers-Perry black holes with arbitrary rotations in general dimensions based on the scattering of a massless scalar field. From the fluxes of the scalar field flowing into the black hole, the changes in mass and angular momenta of the black hole are obtained. However, the extremal and near-extremal black holes with the aforementioned changes are still black holes in the final state. Hence, the conjecture is valid for our investigation. Furthermore, we analyze the changes in the black hole from a thermodynamic perspective to highlight that the laws of thermodynamics support the conjecture.

Automated summary

We investigate the weak cosmic censorship conjecture in Myers-Perry black holes in general dimensions using the scattering of a massless scalar field. By analyzing the fluxes of the scalar field into the black hole and the changes in mass and angular momenta of the black hole, we find that the conjecture holds true. Moreover, the changes in the black hole are also examined from a thermodynamic perspective, which further supports the conjecture.
