Degenerations in convex projective geometry and non-archimedean ordered fields
De Anne Parreau
I will explain how convex projective geometry over ordered non-archimedean fields may be used to study large scale properties of individual real Hilbert geometries and degenerations of convex projective actions. For example, by studying the case of polytopes, we obtain an explicit description of the asymptotic cones of real polytopes.
This is joint work with Xenia Flamm.
