Description
Both boundary CFT causality and hyperbolicity of the
bulk equations of motion constrain the coupling constant for
Gauss-Bonnet gravity. We study these constraints for small
black holes in AdS5. If we rule out solutions that violate
local hyperbolicity via a `hyperbolicity censorship
hypothesis', then we find the parameter space is not
restricted beyond the $\lambda \lesssim 9/100$ limit from
planar black holes.
