and the Maximally Symmetric (3, 8) Distribution with 6-Dimensional Square
Nicklas Day, Boris Doubrov, Igor Zelenko
In 1910, Ãlie Cartan famously realized the split real form of the exceptional Lie group as the symmetry group of the maximally symmetric rank 2 distribution on a 5-dimension…

Generalized pseudo-product structures and finite type distributions via abnormal extremals
Boris Doubrov, Igor Zelenko
We generalize the classical Tanaka result on the finiteness of symmetry algebra for non-degenerate pseudo-product structures to the case when the completely-integrable distribution…

Symplectification of Rank 2 Distributions, Normal Cartan Connections, and Cartan Prolongations
Nicklas Day, Boris Doubrov, Igor Zelenko
We study the Doubrov--Zelenko symplectification procedure for rank distributions with -dimensional cube -- originally motivated by optimal control theory -- through the lens…
