Duality and Hidden Symmetries in Gravitational Theories,ng theories in ten dimensions, hoped to be just different limits of one unique eleven dimensional theory [.]. The main role of duality is to relate two different regimes— e.g. one of weak and one of strong coupling— of these theories. In most cases duality is not a very precise concept, just because

Time-Independent Gravitational Fields,eat are isolated bodies at rest or in uniform rotation in an otherwise empty universe. In such cases one expects the gravitational field to have no “independent degrees of freedom”. Very loosely speaking, the spacetime geometry should be uniquely determined by the matter content of the model under c

Gravitational Lensing from a Geometric Viewpoint, a time- like curve γ (worldline of a light source) in a 4-dimensional Lorentzian manifold (spacetime) and we investigate how many past-pointing lightlike geodesics (light rays) go from ρ to γ. If there is more than one such geodesic, then we are in a gravitational lensing situation. Among other thi
