摘要
运用递归序列、平方剩余以及Pell方程的性质,证明了丢番图方程X2-3(Y2+1)2=46仅有非负整数解(X,Y)=(7,0),(11,2),(164 311,308).同时获得椭圆曲线y2=(x-2)(x2+2x+139)的全部整数点为(x,y)=(2,0),(14,±66),(284 594,±151 823 364).
Properties of Pell equations, recurrent sequence and quadratic residue are used to prove that biophantine equation X2-3 (y2 + 1 ) 2 = 46 has only nonnegative integer solutions (X, Y) = (7,0), (11,2), (164311,308 ). Additionary, all integral points of the elliptic curve y2 = (x -2)(x= + 2x + 139) are obtained.
