We derive the general equations of motion for a braneworld containing a (localized) domain
wall. Euclideanization gives the geometry for braneworld false vacuum decay. We explicitly …

The vector and tensor fluctuations of vortices localizing gravity in the context of the six-
dimensional Abelian Higgs model are studied. These stringlike solutions break …

We present regular solutions for a brane world scenario in the form of a't Hooft–Polyakov
monopole living in the three-dimensional spherically symmetric transverse space of a seven …

In this paper we develop a formalism to analyze the spectrum of small perturbations about
arbitrary solutions of Einstein, Yang–Mills and scalar systems. We consider a general …

We analyse the fluctuations of Nielsen–Olesen vortices arising in the six-dimensional
Abelian–Higgs model. The regular geometry generated by the defect breaks spontaneously …

We analyse the spacetime structure of the global vortex and its maximal analytic extension
in an arbitrary number of spacetime dimensions. We find that the vortex compactifies space …

We consider branes embedded in spacetimes of codimension 1 and 2, with a warped metric
tensor for the subspace parallel to the brane. We study a variety of brane-world solutions …

We construct a family of (p+ 3)-dimensional brane worlds in which the brane has one
compact extra dimension, the bulk has two extra dimensions, and the bulk closes regularly …

We apply the spacetime dependent lagrangian formalism [1] to the action in general
relativity. We obtain Barriola-Vilenkin [BV][2] type of topological solution by exploiting the …

We study global defects coupled to higher-dimensional gravity with a negative cosmological
constant. This paper is mainly devoted to studying global black brane solutions which are …
