Abstract
We investigate the non-Abelian target space duals of Taub-NUT space. T his space has the local isometry group SU(2) x U(1), the action of whi ch has fixed points. We dualize over the entire symmetry group as well as the subgroups SO(3) and U(1), presenting unusual new solutions to low-energy string theory. The solutions are shown to have similar prop erties to C-metrics and monopole spacetimes, and they highlight the re lationship between fixed points of an isometry in one solution and sin gular points in another. We also find the interesting results that, in this case, the U(1) and SO(3) duality procedures commute with each ot her, and that the extreme points of the O(1, 1) duality group for the time translations have special significance under the SO(3) duality.
