We study reparametrization-invariant systems, mainly the relativistic particle and its D-dimensional extended object generalization– d-brane. The corresponding matter Lagrangians naturally contain background interactions, like electromagnetism and gravity. For a dbrane that doesn’t alter the background fields, we define non-relativistic equations assuming… (More)
