1306.3725 (Yun Soo Myung)

Stability of Schwarzschild black holes in fourth-order gravity revisited    [PDF]

Yun Soo Myung
We revisit the classical stability of Schwarzschild black hole in fourth-order theories of gravity. On the contrary of the stability of this black hole, it turns out that the linearized perturbations exhibit unstable modes featuring the Gregory-Laflamme instability of five-dimensional black string. This shows clearly an instability of black hole in fourth-order gravity with $\alpha=-\beta/3$.
