The Cayley cubic and differential equations
Wojciech Kryński, Omid Makhmali
We define Cayley structures as a field of Cayley's ruled cubic surfaces over a four dimensional manifold and motivate their study by showing their similarity to indefinite conforma…
Invariants of contact sub-pseudo-Riemannian structures and Einstein-Weyl geometry
Marek Grochowski, Wojciech Krynski
We consider local geometry of sub-pseudo-Riemannian structures on contact manifolds. We construct fundamental invariants of the structures and show that the structures give rise to…
Canonical frames for Gl(2)-structures
Wojciech Krynski
We construct a canonical frame for an arbitrary Gl(2)-structure thus solving the equivalence problem for Gl(2)-structures. Our treatment includes also a problem of contact equivale…
Parabolic (3,5,6)-distributions and Gl(2)-structures
Wojciech Krynski
We consider rank 3 distributions with growth vector (3,5,6). The class of such distributions splits into three subclasses: parabolic, hyperbolic and elliptic. In the present paper,…
