Thermodynamic geometry of black holes in f(R) gravity [PDF]
, 2016 In this paper, we consider three types (static, static charged and rotating charged) of black holes in f(R) gravity. We study the thermodynamical behavior, stability conditions and phase transition of these black holes.

Perturbations and Stability of Static Black Holes in Higher Dimensions [PDF]
, 1999 In this chapter we consider perturbations and stability of higher dimensional black holes focusing on the static background case. We first review a gauge-invariant formalism for linear perturbations in a fairly generic class of (m+n)-dimensional ...

Stability of the solutions of the Gross-Pitaevskii equation
, 2005 We examine the static and dynamic stability of the solutions of the Gross-Pitaevskii equation and demonstrate the intimate connection between them. All salient features related to dynamic stability are reflected systematically in static properties.
