Worldvolume Dynamics of Branes
  In this PhD thesis the low energy effective actions for D-branes and the M5-brane are used to analyze the dynamics of brane probes moving in the geometry created by diverse supergravity backgrounds. It begins with an introduction to string theory. Brane effective actions with local kappa symmetry are also reviewed. We then study the embedding of D(8-p)-branes in the background geometry of parallel Dp-branes. A BPS condition is found and the analytical solutions describe embeddings which represent branes joined by tubes, which are bundles of fundamental strings. We continue with the analysis of branes partially wrapped on spheres in the near-horizon geometry of branes and bound states. There is a finite number of static configurations as a consequence of a quantization rule for the worldvolume gauge field. These configurations can be interpretated as bound states and this is checked directly in a particular case by using the Myers polarization mechanism. Finally we find configurations of brane probes which behave as massless particles in the geometry of non-threshold bound states. They can be interpreted as gravitons blown up into a fuzzy sphere and sharing some directions with the background.
