Query: Generalised Functions and Distributional Curvature of Cosmic Strings   A new method is presented for assigning distributional curvature, in an
invariant manner, to a space-time of low differentiability, using the
techniques of Colombeau's `new generalised functions'. The method is applied to
show that curvature of a cone is equivalent to a delta function. The same is
true under small enough perturbations.
