Let p be an odd prime. By using the elementary methods we prove that: (1) if 2 ∤ x, p = ±3 (mod 8), the Diophantine equation (2x − 1)(py − 1) = 2z2 has no positive integer solution except when p = 3 or p is of the form \(p = 2a_0^2 + 1\), where a0 > 1 is an odd positive integer. (2) if 2 ∤ x, 2 ∣; y, y ≠ 2, 4, then the Diophantine equation (2x − 1)(py − 1) = 2z2 has no positive integer solution.

关于丢番图方程(2 x − 1)(py − 1)= 2 z 2

p为奇质数。通过使用基本方法,我们证明:(1)如果2∤x ,p =±3(mod 8),则丢丢丁方程(2 x − 1)(p y − 1)= 2 z 2没有正整数解除了当p = 3或p的形式为\(p值= 2a_0 ^ 2 + 1 \) ,其中一个0 > 1为奇数正整数。(2)如果2∤ X,2 |; y,y ≠2、4,则丢番图方程(2 x − 1)(p y − 1)= 2 z 2没有正整数解。
