Computing integral points on X_ns^+(p)

Number Theory 2021-05-26 v4

Abstract

We describe an algorithm for computing integral points on the modular curve of prime level p associated to the normalizer of a non-split Cartan subgroup of GL_2(F_p). Using our method, we show that for 7<p<101 the only integral points on this curve are the CM-points.
