Free 3-distributions: holonomy, Fefferman constructions and dual distributions
Stuart Armstrong
This paper analyses the parabolic geometries generated by a free 3-distribution in the tangent space of a manifold. It shows the existence of normal Fefferman constructions over CR…

Free -distributions: holonomy, sub-Riemannian structures, Fefferman constructions and dual distributions
Stuart Armstrong
This paper analyses the parabolic geometries generated by a free -distribution in the tangent space of a manifold. It shows that certain holonomy reductions of the associated no…

Generalised Einstein condition and cone construction for parabolic geometries
Stuart Armstrong
This paper attempts to define a generalisation of the standard Einstein condition (in conformal/metric geometry) to any parabolic geometry. To do so, it shows that any preserved in…
