Towards a Gravitational Analog to S-duality in Non-abelian Gauge Theories
arXiv:hep-th/9711115 · doi:10.1103/PhysRevD.57.7501
Abstract
For non-abelian non-supersymmetric gauge theories, generic dual theories have been constructed. In these theories the couplings appear inverted. However, they do not possess a Yang-Mills structure but rather are a kind of non-linear sigma model. It is shown that for a topological gravitational model an analog to this duality exists.
