Some Criteria for Class Numbers to Be Non-One

open access: yesJournal of Mathematics, 2020
Let d be a positive integer which is not a perfect square and n be any nonzero fixed integer. Then, the equation x2−dy2=n is known as the general Pell equation. In this paper, we give some criteria for class numbers of certain real quadratic fields to be

The polynomial Pell equation

open access: yesElemente der Mathematik, 2004
The classic problem of Diophantine approximations consists in discovering good rational-\-numbered approximations of quadratic irrationalities of the form \(\sqrt d\), where \(d\) is a square-free natural number. This problem leads to the Pell equation \(x^2 - dy^2 = 1\) in whole integers \(x, y\). It turns out that you can acquire all solutions from a
