Some of the solitonic or lump solutions that we study here are the (p,q) cosmic strings and their junctions, cosmic necklaces and semi-local strings and generic semi-local defects. We show how various wrapping modes of D3-branes may be used to study all these defects in one interpolating set-up. Our construction allows us to study (p,q)-string junctions in curved backgrounds and in the presence of non-trivial RR fluxes. We extend the junction construction to allow for the possibility of cosmic necklaces, and show how these new lump solutions form a consistent picture in the inflationary brane models. We also give a generic construction of semi-local defects in these backgrounds, and argue that our construction encompasses all possible constructions of semi-local defects with any global symmetries. The cosmological implications of these configurations are briefly studied.", "revisions": [ { "version": "v3", "updated": "2007-04-19T19:51:14.000Z" } ], "analyses": { "keywords": [ "construction", "cosmic necklaces", "study classical lump solutions", "generic semi-local defects", "non-trivial rr fluxes" ], "tags": [ "journal article" ], "publication": { "publisher": "IOP", "journal": "Journal of High Energy Physics", "year": 2007, "month": "Apr", "volume": 2007, "number": 4, "pages": "093" }, "note": { "typesetting": "TeX", "pages": 31, "language": "en", "license": "arXiv", "status": "editable", "inspire": 745268, "adsabs": "2007JHEP...04..093D" } } }
