摘    要:设p,q是互异的奇素数,p≡q≡1 (mod 6),利用递归序列、Pell方程的解的性质、Maple小程序等方法证明了不定方程组x-1=6pqu2,x2+x+1=3v2仅有平凡解(x,u,v)=(1,0,±1);而不定方程组x+1=6pqu2,x2-x+1=3v2仅有平凡解(x,u,v)=(-1,0,±1).

关 键 词:不定方程  Pell方程  奇素数  整数解  递归序列

Abstract:Let p,q be different odd primes,p ≡ q ≡ 1 (mod 6).With the help of recursive sequence,some properties of the solutions to Pell equation and Maple formality,the only integer solution in integers of the indefinite equations x-1 =6pqu2,x2 + x + 1 =3v2 was x =1,u =0,v =± 1,and the only integer solution of the indefinite equations x + 1 =6pqu2,x2-x + 1 =3v2 was x =-1,u =0,v =± 1.
Keywords:indefinite equation  Pell equation  odd prime  integer solution  recursive sequence
