A thick Z_2-symmetric domain wall supported by a scalar field with an arbitrary potential V
(\phi) in 5D general relativity is considered as a candidate brane world. We show that, under …

We present a brane-world scenario in which two regions of AdS 5 space-time are glued
together along a 3-brane with constant positive curvature such that all spatial dimensions …

Numerical solutions of Einstein, scalar, and gauge field equations are found for static and
inflating defects in a higher-dimensional spacetime. The defects have (3+ 1)-dimensional …

We investigate the stability of inflating branes embedded in an O (2) texture formed in one
extra dimension. The model contains two 3-branes of nonzero tension, and the extra …

We present full numerical solutions to the system of a global string embedded in a six-
dimensional space-time. The solutions are regular everywhere and do confine gravity in our …

The cosmological two brane model is discussed in detail. An elegant method for deriving the
generalised non-linear equations for the interbrane distance is presented. These equations …

Abstract We study O (N+ 1) nonlinear σ-model in (p+ 1+ N)-dimensional curved spacetime
with a negative cosmological constant, and find a new σ-lump solution with half-integer …

We consider a complex scalar field in (p+ 3)-dimensional bulk with a negative cosmological
constant and study global vortices in two extra-dimensions. We reexamine carefully the …
