设m为正整数,p为奇素数。利用Pell方程和四次丢番图方程的一些性质和初等数论方法,证明了方程组x2 −(4 m2 − 1)y2 = 1和y2 − pz 2 = 1有正整数解(x,y,z)当且仅当p <$7(mod 8)且其中(f,g)是方程f2 − pg 2 = 2的正整数解.此外,如果满足上述条件,则方程组只有正整数解。
AbstractLet m be a positive integer, and let p be an odd prime. By using certain properties of Pell and quartic diophantine equations with some elementary number theory methods, we prove that the system of equations x2 − (4m2 − 1)y2 = 1 and y2 − pz2 = 1 has positive integer solutions (x, y, z) if and only if p ≡ 7(mod 8) and , where (f, g) is a positive integer solution of the equation f 2 −pg2 = 2. Further, if the above condition is satisfied, then the system of equations has only the positive integer solution .
