ABSTRACT: We will introduce intrinsic Lipschitz hypersurfaces in Carnot-Carathéodory spaces and prove that intrinsic Lipschitz domains have locally finite perimeter. We will also show the existence of a boundary trace operator for functions of bounded variation on Lipschitz domains and obtain extension results for such functions.
