Abstract
Gauss-Bonnet gravity is a natural generalization of general relativity which includes higher order curvature terms and obeys Lovelock’s theorem. However, unlike Einstein equations, the gravitational equations in Gauss-Bonnet gravity are not quasi-linear any more. A lot of differences arise due to this point. In this talk, I will discuss the exact solutions in this theory and the construction of general gauge invariant perturbation theory. Based on these, the dynamical stability and the quasi-normal modes (QNMs) spectral stability of the black holes will be discussed.
