Geometria em Lisboa 1 April 2003, 17h00 Abstract: We shall describe in this seminar the initial value formulation of Einstein's equations, which yields an evolution problem for a Riemannian metric on a 3-manifold. This formulation will then be used to construct "warp drive" type solutions, which allow arbitrarily high effective speeds. Properties of these solutions will be analysed.
