Abstract :
The purpose of this paper is to continue the study of the class of models proposed in a previous letter. The model corresponds to a system of branes of diverse dimensionalities with Chern–Simons actions for a supergroup, embedded in a background described also by a Chern–Simons action. The model treats the background and the branes on an equal footing, providing a “brane-target space democracy”. Here we suggest some possible extensions of the original model, and discuss its equations of motion, as well as the issue of currents and charges carried by the branes. We also discuss the relationship with M-theory and Superstring theory.
