Spinors in Five-Dimensional Contact Geometry
We use classical (Penrose) two-component spinors to set up the differential geometry of two parabolic contact structures in five dimensions, namely ₂ contact geometry and Legendrean contact geometry. The key players in these two geometries are invariantly defined directional derivatives defined only...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | We use classical (Penrose) two-component spinors to set up the differential geometry of two parabolic contact structures in five dimensions, namely ₂ contact geometry and Legendrean contact geometry. The key players in these two geometries are invariantly defined directional derivatives defined only in the contact directions. We explain how to define them and their usage in constructing basic invariants, such as the harmonic curvature, the obstruction to being locally flat from the parabolic viewpoint. As an application, we calculate the invariant torsion of the ₂ contact structure on the configuration space of a flying saucer (always a five-dimensional contact manifold).
