Projective geometry of 3-Sasaki structures
A. Rod Gover, Katharina Neusser, Travis Willse
We show that -Sasaki structures admit a natural description in terms of projective differential geometry. This description provides a concrete link between -Sasaki structures…
Chains of path geometries on surfaces: theory and examples
Gil Bor, Travis Willse
We derive the equations of chains for path geometries on surfaces by solving the equivalence problem of a related structure: sub-Riemannian geometry of signature on a conta…
Homogeneous Real (2,3,5) Distributions with Isotropy
Travis Willse
We classify multiply transitive homogeneous real (2,3,5) distributions up to local diffeomorphism equivalence.
Projective geometry of Sasaki-Einstein structures and their compactification
A. Rod Gover, Katharina Neusser, Travis Willse
We show that the standard definitions of Sasaki structures have elegant and simplifying interpretations in terms of projective differential geometry. For Sasaki-Einstein structures…
The almost Einstein operator for distributions
Katja Sagerschnig, Travis Willse
For the geometry of oriented distributions , which correspond to regular, normal parabolic geometries of type for a particular par…
