Duality of (2,3,5)-distributions and Lagrangian cone structures

Goo Ishikawa, Yumiko Kitagawa, Asahi Tsuchida +1

As was shown by a part of the authors, for a given $(2, 3, 5)$ -distribution $D$ on a $5$ -dimensional manifold $Y$ , there is, locally, a Lagrangian cone structure $C$ on another $5$ …

Duality on geodesics of Cartan distributions and sub-Riemannian pseudo-product structures

G. Ishikawa, Y. Kitagawa, W. Yukuno

Given a five dimensional space endowed with a Cartan distribution, the abnormal geodesics form another five dimensional space with a cone structure. Then it is shown, if the cone s…

Duality of singular paths for (2,3,5)-distributions

Goo Ishikawa, Yumiko Kitagawa, Wataru Yukuno

We show a duality which arises from distributions of Cartan type, having growth (2, 3, 5), from the view point of geometric control theory. In fact we consider the space of singula…
