Resumen:
In this paper we generalize previous result regarding the stability under gravitational perturbations of superextreme Kerr space-time wich has a naked singularity and black hole interior beyond the Cauchy horizon. To do so we study solutions to the radial and agular Teukolsky's equations with different spin weight, particulary s = ±1 representing electromagnetic perturbations, s = ±1/2 representing a perturbation by a Dirac field ans s = 0 representing perturbations by a scalar field. By analizing the properties of radial and angular eigenvalues we prove the existence of an infinite family of unstable modes.
