A Note on the Finiteness of Curvature at Cosmic String Cusps
Ruth Gregory
We examine a Nambu-Goto string trajectory in the neighbourhood of a cusp and determine the extrinsic curvature invariants. These are demonstrated to be finite, in contradiction wit…
Curvature Corrections to Dynamics of Domain Walls
Brandon Carter, Ruth Gregory
The most usual procedure for deriving curvature corrections to effective actions for topological defects is subjected to a critical reappraisal. A logically unjustified step (leadi…
Evidence for the Stability of Extremal Black p-Branes
Ruth Gregory, Raymond Laflamme
We investigate the stability of the extremal black p-brane which contains a n-form and a dilaton. We show that the instability due to the s-mode, which was present in the uncharged…
The Instability of Charged Black Strings and p-Branes
Ruth Gregory, Raymond Laflamme
We investigate the evolution of small perturbations around charged black strings and branes which are solutions of low energy string theory. We give the details of the analysis for…
