03

Flow to IR region characterized by specific horizon structure.

Abstract

We study $N = 2$ gauged supergravity with $U (1)$ gauge group coupled to $n_{v}$ vector multiplets and find quite general analytic solutions for quarter-BPS black holes with mass, NUT and dyonic Maxwell charges. The solutions we find have running scalar fields and flow in the IR region to a horizon geometry of the form AdS $_{2} \times Σ_{g}$ .
