关于丢番图方程x3±1=pD1 y2
On the Diophantine equation x3±1=pD1 y2
摘要
Abstract
Let D1 be an non-square positive integer, p=1(mod 6), and p be an odd prime. By using the minimal solution to the Pell equation px2-3y2=1, congruent formula, quadratic residue, and the properties of Legendre symbol, the sufficient conditions were obtained that the Diophantine equation x3±1=pD1 y2 has no integer solutions, where D1 could not be exactly divided by the prime number 3 or 6k+1, p=3n(n+1)+1.关键词
