Minimum mass, maximum charge and hyperbolicity in scalar Gauss-Bonnet gravity
Dario Rossi, Leonardo Gualtieri, Thomas P. Sotiriou
We study the loss of hyperbolicity of perturbation equations for black hole solutions of scalar Gauss-Bonnet gravity. We consider a class of coupling functions allowing for static…
