Rational points on elliptic and hyperelliptic curves

Research output: Chapter in Book/Report/Conference proceedingConference contribution


A hyperelliptic curve C over Q is the graph of an equation of the form y2 = f(x), where f is a polynomial having coefficients in the rational numbers Q and distinct roots in C. The special case where the degree of f is 3 is called an elliptic curve E over Q which, as we will discuss, has many special properties not shared by general hyperelliptic curves C. A solution (x, y) to C: y2 = f(x), with x and y rational numbers, is called a rational point on C. Given a random elliptic or hyperelliptic curve C: y2 = f(x) over Q with f(x) of a given degree n, how many rational points do we expect on the curve C? Equivalently, how often do we expect a random polynomial f(x) of degree n to take a square value over the rational numbers? In this article, we give an overview of a number of recent conjectures and theorems giving some answers and partial answers to this question.
