Abstract

We derive Bogomolny equations for an Einstein-Yang-Mills-dilaton-σ\sigma model (EYMD-σ\sigma) on a static spacetime, showing that the Einstein equations are satisfied if and only if the associated (conformally scaled) three-metric is flat. These are precisely the static metrics for which super-covariantly constant spinors exist. We study some general properties of these equations and then consider the problem of obtaining axially symmetric solutions for the gauge group SU(2).
