This paper gives a comprehensive review on thick brane solutions and related topics. Such
models have attracted much attention from many aspects since the birth of the brane world …

We present a metric solution in six dimensions, where gravity is localized on a four-
dimensional singular stringlike defect. The corrections to four-dimensional gravity from the …

We discuss possible variations of the effective gravitational constant with length scale,
predicted by most of alternative theories of gravity and unified models of physical …

Starting from a completely general standpoint, we find the most general brane-universe
solutions for a 3-brane in a five-dimensional spacetime. The brane can border regions of …

At the beginning of the 20th century, only two physical fields were known, the
electromagnetic and gravitational ones. Einstein's theory of special relativity (SR), created in …

We demonstrate that the initial conditions for inflation are met when a D 5− D 5 brane
annihilates. This scenario uses Sen's conjecture that a codimension two vortex forms on the …

After presenting string-like solutions with a warp factor to Einstein's equations, we study
localization of various spin fields on a string-like defect in a general space–time dimension …

We show how to extend the usual black string instability of vacuum or charged black p-
branes to the anti-de Sitter background. The string fragments in an analogous fashion to the …

A generalization of the Bardeen formalism to the case of warped geometries is presented.
The system determining the gauge-invariant fluctuations of the metric induced by the scalar …

We consider spherically symmetric higher-dimensional solutions of Einstein's equations with
a bulk cosmological constant and n transverse dimensions. In contrast to the case of one or …
