abstract: 

We extend the explicit quadratic Chabauty methods developed in previous work by the first two authors to the case of non-hyperelliptic curves. This results in a method to compute a finite set of p-adic points, containing the rational points, on a curve of genus g > 2 over the rationals whose Jacobian has Mordell–Weil rank g and Picard number greater than one, and which satisfies some additional conditions. This is then applied to determine the rational points of the modular curve Xs (13), completing the classification of non-CM elliptic curves over Q with split Cartan level structure due to Bilu–Parent and Bilu–Parent–Rebolledo.
