UBC Number Theory Seminar: Shabnam Akhtari
Topic
Representation of Integers by Binary Forms
Speakers
Details
Let F(x, y) be a binary form of degree at least 3 which is irreducible over the rationals. For any fixed non-zero integer m, Thue showed that the equation F(x, y) =m has at most finitely many solutions in integers x, y. I will discuss some fundamental work on bounding the number of integral solutions of such equations, which I learned during my graduate study at UBC. Then I will share some of my related results, including some current work in progress which aims to improve upper bounds on the number of solutions of index (and discriminant) form equations in quartic number fields.
