关于丢番图方程x^2－Dy^n＝1

On the Diophantine Equation x 2-Dy n=1

本文将对Ｄ的一些情形，研究不定方程ｘ２－Ｄｙ４＝１解的情况。

This paper studies the solutions of the Diophantine equation x 2-Dy 4=1 in some case with D , no be inperfec square and give the necessary and sufficient condition for the Diophantine equation x 2-Dy n=1 to have a integer solution with xy ≠0.
