摘要
应用因子分解法、简单同余法以及前人的已知结果证明了:(1)设p是1个奇素数,则丢番图方程组x+1=3py21,x2-x+1=3y22,(y1,y2)=1,y1>0,y2>0,无正整数解x,p,y1,y2;(2)丢番图方程x3+1=py2(其中p≡-1(mod 3)为素数)仅有整数解(x,y)=(-1,0);(3)丢番图方程x3-1=py2(其中p≡-1(m od 3)为素数)仅有整数解(x,y)=(1,0).
In the paper, we have proved the following (1) the Diuphantine equations x+1=3py^2;x^2-x+1=3y2^2;,(y1,y2)=1,y1〉0,y2〉0,where p was an odd prime number, has no positive integer solution x,p,y1,y2; (2) the Diuphantine equation x+1=3py^2, integer solution (x,y) = (- 1,0). ( 3 ) the Diuphantine equation x3 - 1 integer solution ( x , y ) = (1,0). 2 py , where p≡- 1 ( rood 3 ) was an odd prime number, has only integer solution (x,y) = (-1,0).( 3 ) the Diuphantine equation X^3-1=py^2,, where p = - 1 ( mod 3 ) was an odd prime number, has only integer solution ( x , y ) = (1,0).
