Geometric surgeries of three-dimensional flag structures and non-uniformizable examples
Elisha Falbel, Martin Mion-Mouton
In this paper, we introduce a notion of geometric surgery for flag structures, which are geometric structures locally modelled on the three-dimensional flag space under the action…
A global invariant for path structures and second order differential equations
Elisha Falbel, Jose Miguel Veloso
We study a global invariant for path structures. The invariant is obtained as a secondary invariant from a Cartan connection on a canonical bundle associated to a path structure. I…
Closed ray nil-affine manifolds and parabolic geometries
Raphaël Alexandre
Ray nil-affine geometries are defined on nilpotent spaces. They occur in every parabolic geometry and in those cases, the nilpotent space is an open dense subset of the correspondi…
Closed ray affine manifolds
Raphaël Alexandre
We consider closed manifolds that possess a so called rank one ray structure. That is a (flat) affine structure such that the linear part is given by the products of a diagonal tra…
Cartan connections and path structures with large automorphisms groups
Elisha Falbel, Martin Mion-Mouton, Jose Miguel Veloso
We classify compact manifolds of dimension three equipped with a path structure and a fixed contact form (which we refer to as a strict path structure) under the hypothesis that th…
Redundancy of triangle groups in spherical CR representations
Raphaël Alexandre
Falbel, Koseleff and Rouillier computed a large number of boundary unipotent CR representations of fundamental groups of non compact three-manifolds. Those representations are not…
Flag structures on real 3-manifolds
E Falbel, J Veloso
We define flag structures on a real three manifold M as the choice of two complex lines on the complexified tangent space at each point of M. We suppose that the plane field define…
