Enhanced models of inflating branes with topological defects

Abstract

We study brane world models which contain local topological defects in the bulk and a (3+1)-dimensional inflating brane. We put the emphasis on new types of solutions that are periodic in the bulk radial coordinate and thus provide examples of "naturally compactified" brane worlds.
