摘要 利用同余、奇偶分析、二次同余式及二元二次方程解的结构及解序列的递归性质等初等方法,证明了椭圆曲线y 2=x 3+49x-106的全部整数点为x,y=(2,0),11,±42. Using elementary methods including the properties of congruent,parity analysis,quadratic congruence,structure and sequence of solution for binary quadric equation,the elliptic curve only has positive integral point 11,42 was proved.
