U-duality and non-BPS solutions
arXiv:1012.4803 · doi:10.1007/JHEP02(2011)074
Abstract
We derive the explicit action of the U-duality group of the STU model on both BPS and non-BPS extremal multi-center solutions. As the class of known non-BPS extremal solutions is not closed under U-duality, we generate in this way new solutions. These should represent the most general class of extremal non-BPS multi-center under-rotating solutions of the STU model.
