Description
In this work, we re-discover a way to formulate gravity in terms of Weyl-spinor-valued variables. Not only does this allow for edge data upon discretization (in contrast to the conventional area-data in 4d spin-foam theory), but it also has a beautiful link to a topological theory via a new set of constraints.
