ChaBONNty conference We discuss a geometric quadratic Chabauty algorithm for the normalizers of non-split Cartan curves. The method approaches the problem of finding rational points from a modular point of view: in particular, we do not use defining equations for the curves. The first challenge is to describe the Poincaré torsor in such a way.
This is joint work with Khuri-Makdisi, Hashimoto, Lombardo, Mascot, and Parent.
