摘要: |
在不定方程(组)的研究中,整数解的绝对值的上界确定是一个重要的问题,因为一旦知道了这一上界,从理论上讲,只要把界内的整数代入原方程(组)一一验算,即可得全部整数解.运用Baker方法得到了不定方程组5x2-3y2=2,16y2-5z2=11的正整数解的上界为1218390. |

Abstract: |
By Baker's method,this paper solves the upper bound for the positive integer solutions of Diophantine equations 7x~2-5y~2=2,24y~2-7z~2=17.And the upper bound for y is 12~(18~(390)). |
Key words: a system of Diophantine equations,the upper bound of solutions,Baker's method |
