Quantitativity on the number of rational points in the Mordell conjecture

a day ago

Mathematicians have made a significant breakthrough in understanding rational points on curves, a fundamental problem in number theory.
Rational points are coordinates on curves that are either whole numbers or fractions, and their study has implications in cryptography and other fields.
A recent preprint by three Chinese mathematicians establishes the first hard upper limit on the number of rational points any curve can have, marking a major advancement.
The new formula applies universally to all curves, depending only on the curve's degree and its Jacobian variety, a related mathematical construct.
This development builds on Louis Mordell's 1922 conjecture, later proven by Gerd Faltings, which stated that curves of degree 4 or higher have a finite number of rational points.
The result opens new avenues for research in higher-dimensional mathematical objects like manifolds, which are crucial in both mathematics and theoretical physics.
The breakthrough is part of a broader surge in progress on understanding rational points, signaling an exciting phase in this ancient mathematical quest.
