In the present work we investigate the physical interpretation of gravitational perturbations of static asymptotically anti-de Sitter black holes with non-spherical topology. For zero wavenumber modes, the axial perturbations yield only small rotations on the system, while the polar perturbations lead to a change in the mass and may also produce gravitational waves. Additionally, it is verified that perturbations with any nonzero wavenumber are able to produce gravitational waves in these space–times. On the basis of these results, the quasinormal frequencies corresponding to polar perturbation modes with null wavenumber are calculated and briefly analyzed.

AbstractIn this work, we investigate the quasinormal frequencies of a class of regular black hole solutions which generalize Bardeen and Hayward spacetimes. In particular, we analyze scalar, vector and gravitational perturbations of the black hole with the semianalytic WKB method. We analyze in detail the behaviour of the spectrum depending on the parameter p/q of the black hole, the quantum number of angular momentum and the s number. In addition, we compare our results with the classical solution valid for $$p = q = 1$$ p = q = 1 .

We discuss the P−V criticality and phase transition in the extended phase space of anti-de Sitter(AdS) black holes in four-dimensional Rastall theory and recover the Van der Waals (VdW) analogy of small/large black hole (SBH/LBH) phase transition when the parameters ωs and ψ satisfy some certain conditions. Later, we further explore the quasinormal modes (QNMs) of massless scalar perturbations to probe the SBH/LBH phase transition. It is found that it can be detected near the critical point, where the slopes of the QNM frequencies change drastically in small and large black holes.
