Abstract

Extremal black holes in Maxwell‐Einstein supergravities with scalar fields can be obtained as solutions of first order flow equations even when they are not supersymmetric, provided one identifies a suitable superpotential W entering the effective potential, and driving the evolution of the scalar fields. We briefly review the main ideas for the construction of W in terms of duality invariants of N = 2 special geometry and we comment on its properties in wider contexts.

## Abstract We study extremal charged black hole solutions in two dimensional type 0A string theory using the low energy effective gravity theory, and then attempt to identify them in the exact matrix model description of the theory. In particular, we identify a static Fermi sea configuration of ma
