Maximally degenerate Weyl tensors in Riemannian and Lorentzian signatures
Boris Doubrov, Dennis The
We establish the submaximal symmetry dimension for Riemannian and Lorentzian conformal structures. The proof is based on enumerating all subalgebras of orthogonal Lie algebras of s…

The gap phenomenon in parabolic geometries
Boris Kruglikov, Dennis The
The infinitesimal symmetry algebra of any Cartan geometry has maximum dimension realized by the flat model, but often this dimension drops significantly when considering non-flat g…
