Brane waves and strings Original Research Article

Recently, solutions of the Born-Infeld theory representing strings emanating from a Dirichlet p-brane have been constructed. We discuss the embedding of these Bom-Infeld solutions into the non-abelian theory appropriate to multiple overlapping p-branes. We also prove supersymmetry of the solutions explicitly in the full non-linear theory. We then study transverse fluctuations, both from the world-brane point of view and by analyzing a test string in the supergravity background of a Dp-brane. We find agreement between the two approaches for the cases p = 3,4.
