Abstract

A dynamical description of the transitions between different backgrounds requires the existence of a background independent action which propagates the correct number of degrees of freedom and couples bulk supergravity to certain higher dimensional branes. We present classical equations for configurations that separate the world into regions with different flux parameters etc. and discuss the difficulties of trying to construct an action that describes the transitions between them within the framework of supergravity.
