Generalized functions and distributional curvature of cosmic strings
May, 1996Citations per year
Abstract: (arXiv)
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.- astrophysics: string
