Topic: Uniformity in the number of rational points on curves
Abstract: This mini-course aims to prove the result of Dimitrov-Gao-Habegger on a rather uniform bound on the number of rational points on curves, which depends only on the genus, the degree of the number field, and the Mordell-Weil rank of the Jacobian. We will start by recalling Vojta's proof of the Mordell conjecture, and then prove the height inequality of Gao-Habegger and Dimitrov-Gao-Habegger using the recent work of Yuan-Zhang on adelic line bundles, and finally prove the geometric bigness of the tautological adelic line bundle by studying the generic Betti rank. This last part relies on some functional transcendence result. In the end, we will briefly discuss a more recent work of Gao-Zhang on the Beilinson-Bloch height of the Gross-Schoen cycles.
