Abstract :
We analyze the Hessian matrix of the black hole potential of image, image supergravity, and determine its rank at non-BPS critical points, relating the resulting spectrum to non-BPS solutions (with non-vanishing central charge) of image, image magic supergravities and their “mirror” duals. We find agreement with the known degeneracy splitting of image non-BPS spectrum of generic special Kähler geometries with cubic holomorphic prepotential. We also relate non-BPS critical points with vanishing central charge in image magic supergravities to a particular reduction of the image, image-BPS critical points.
