Scalar field perturbations in asymptotically Lifshitz black holes
We consider scalar field perturbations about asymptotically Lifshitz black holes with dynamical exponent z in D dimensions. We show that, for suitable boundary conditions, these Lifshitz black holes are stable under scalar field perturbations. For z≥2, we explicitly compute the quasinormal mode freq...
