O-minimality and the Sub-Riemannian Sphere

Erik Walsberg

Abstract: I will discuss an interesting connection I recently found between Sub-riemannian geometry and o-minimality. In short: sub-riemannian geometers believe that the spheres in real analytic sub-riemannian metrics are definable in some o-minimal expansion of the real field. Furthermore, people in o-minimality are trying to construct the kind of o-minimal expansion that the sub-riemannian geometry are looking for, It seems that the o-minimality community was entirely unaware of this until now. No knowledge of sub-riemannian geometry will be assumed in this talk. Basic knowledge of model theory will be assumed.
