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.
متن کاملDistributional curvature of time dependent cosmic strings
Colombeau’s theory of generalised functions is used to calculate the contributions, at the rotation axis, to the distributional curvature for a time-dependent radiating cosmic string, and hence the mass per unit length of the string source. This mass per unit length is compared with the mass at null infinity, giving evidence for a global energy conservation law.
متن کاملN ov 1 99 8 Distributional torsion of cosmic walls crossed by cosmic strings
Distributional sources of cosmic walls crossed by cosmic strings from Riemann-Cartan (RC) Geometry. The matter density of the planar wall is maximum at the point where the cosmic string crosses the cosmic wall. Cartan torsion is has a support on the cosmic string given by the Dirac δ-function. Off the sources are left with a torsionless vacuum. PACS number(s) : 0420,0450,1127 Departamento de F́ı...
متن کاملCosmic Strings and Cosmic Supertrings
In these lectures, I review the current status of cosmic strings and cosmic superstrings. I first discuss topological defects in the context of Grand Unified Theories, focusing in particular in cosmic strings arising as gauge theory solitons. I discuss the reconciliation between cosmic strings and cosmological inflation, I review cosmic strings dynamics, cosmic string thermodynamics and cosmic ...
متن کاملCosmic Strings & Cosmic Variance
By using a simple analytical model based on counting random multiple impulses inflicted on photons by a network of cosmic strings we show how to construct the general q-point temperature correlation function of the Cosmic Microwave Background radiation. Our analysis is sensible specially for large angular scales where the Kaiser-Stebbins effect is dominant. Then we concentrate our study on the ...
