Abstract
It was demonstrated recently that there is an upper bound of the ChernSimons coupling of the fivedimensional EinsteinMaxwell theory beyond which the electrically charged AdS2 × S 3 vacuum solution becomes unstable We generalize the result to a general class of gravity theories involving ChernSimons and/ or transgression terms and find their upper bounds for stability We show that supergravities with AdS×Sphere vacua satisfy the bounds
