Inequality between size and angular momentum for bodies
Dain, Sergio Alejandro (2014-01-31)A universal inequality that bounds the angular momentum of a body by the square of its size is presented and heuristic physical arguments are given to support it. We prove a version of this inequality, as consequence of ... -
On the linear stability of the extreme Kerr black hole under axially symmetric perturbations
Dain, Sergio Alejandro; Gentile de Austria, Ivan (2014)We prove that for axially symmetric linear gravitational perturbations of the extreme Kerr black hole, there exists a positive definite and conserved energy. This provides a basic criteria for linear stability in axial ...
