Rational Polynomial Pell Equations. [PDF]

open access: yes, 2013
Let R denote either the integers or the rationals and let d(x) be a square-free polynomial in R[x]. In this thesis we study the question of when does the polynomial Pell equation, f(x)^2-d(x)g(x)^2=1 have solutions f(x), g(x) in R[x] with g(x) non-zero.

Continued fractions in function fields: polynomial analogues of McMullen's and Zaremba's conjectures

open access: yes, 2017
We examine the polynomial analogues of McMullen's and Zaremba's conjectures on continued fractions with bounded partial quotients. It has already been proved by Blackburn that if the base field is infinite, then the polynomial analogue of Zaremba's ...
