Supersymmetric configurations in Euclidean Freedman-Schwarz model

Abstract

We study Euclidean D=4, N=4 gauged $SU(2)\times SU(1,1)$ supergravity theory which has been obtained from dimensional reduction of N=1, D=10 supergravity on $S^3\times Ad{S}_3$. We obtain supersymmetric configurations like domain wall, electro-vac type of solutions with geometries $E^2\times S^2$, $E^2\times Ad{S}_2$ and axio-vac type $E^1\times S^3$ solution in this Euclidean Freedman-Schwarz (EFS) model. We also show that the Euclidean gravitational instantons with nontrivial (anti)self-dual U(1) gauge fields are stable vacua preserving one fourth of the original supersymmetry.
