The Hesse potential, the c-map and black hole solutions

arXiv:1112.2876 · doi:10.1007/JHEP07(2012)163

Abstract

We present a new formulation of the local c-map, which makes use of the real formulation of special Kahler geometry and the associated Hesse potential. As an application we use the temporal version of the c-map to derive the black hole attractor equations from geometric properties of the scalar manifold, and we construct various stationary solutions for four-dimensional vector multiplets by lifting instanton solutions of the time-reduced theory.
